lsDancemachine
I wrote my lsDancemachine, because the most common Evil Fool Dancemachine sucks as a newbie trap, espically in combo with tiny dances, and lags the sim.
The lsDancemachine is a client server dancemachine to animate avatars and to cache their permissions. The protocol works region wide, so you can install one lsDancemachine to manage you animations in a central place, and distribute danceballs and other clients anywhere on the simulator. Clients could be in any object. E.g. a wall of multi prim animation vendors could use the lsDancemachine to cache the avatar permission, or several sit targets share the same animation.
The lsDancemachine is, unlike the most most common Evil Fool dancemachine, neither random nor syncron by default, but offers avatars a dialog of animations to choose. Animations with names longer than 24 characters are mapped to fit dialog limits, to allow the use of non-mod animations. Two players are treated special. Prims owned by the owner of the lsDancemachine can command the server and a player who is designated as DJ can command all dancers into a syncron dance of choice.
lsDancemachine Server
The lsDancemachine Server contains the animations, one .lsDanceServer and many .lsDanceXec scripts. The .lsDanceXec scripts must be named as a CSV to contain the slot number starting with 1. e.g. 'lsDanceXec, 1', 'lsDanceXec, 2', ...

Configuration
The lsDancemachine server contains a notecard .lsDancemachine with default configuration :
lsDance=-19 lsDeejay=-17 motto=Schwing das Tanzbein
You most likely want to change the object name of the lsDancemachine server and the motto to give a nice dialog of your choice, and add or remove dances. You might want to change the default negative channels to positive ones, to allow avatars to use them directly and you need to change the lsDance channel, if you group you animations or cluster permissions into several servers.
You can extend this notecard by a [translate] or [dialog] section to translate dialog names to animation names. A [translate] section will only translate those animations named, and offers all other animations untranslated. A [dialog] section restricts the dialog to the named animations, even if there are more animations in the lsDancemachine. Those unnamed animations will then only be available to DJ or owner command scripts. Example:
[translate] Club1=Club Dance 1 (looped) Club2=Club Dance 2 (looped)
this would only translate those two dances, leaving other animation names untouched.
[dialog] Aero=aerobicdance(looped) Boogie=boogie
this would restrict the dialog only to offer 'Aero' and 'Boogie' even if there are more animations available.
Protocol
Avatars talk to the lsDancemachine on lsDance channel, even if this is a negative channel, by replying to a menu dialog. The reply is either "stop", or "next", or "prev" or a selected animation. Normaly everybody chooses their own animation, but the DJ can overwrite this choice and command all dancers into a syncronus animation.
Objects owned by the owner of the lsDancemachine server can also use dance and DJ commands formatted as comma separated lists.
The dance command on lsDance channel has either 3 or 4 elements. The short form will offer a dialog to the avatar, while the later also incudes the animation name. e.g. a typical but short danceball dialog:
[11:12] :lsDanceball 08101: dance,2682eb10-ee55-46a6-bc49-0f09a39d152b,Kephra Nurmi [11:12] Kephra Nurmi: next 09 [11:12] Kephra Nurmi: Groove [11:13] :lsDanceball 08101: dance,2682eb10-ee55-46a6-bc49-0f09a39d152b,Kephra Nurmi [11:13] Kephra Nurmi: stop
while the long form is useful for sit targets or vendors:
[11:15] :Table: dance,2682eb10-ee55-46a6-bc49-0f09a39d152b,Kephra Nurmi,Boogie [11:15] :Table: dance,2682eb10-ee55-46a6-bc49-0f09a39d152b,Kephra Nurmi,stop
the long form could also be used with ,*,* as a wildcard to command all avatars:
[11:15] :DJ: dance,*,*,Boogie [11:15] :DJ: dance,*,*,stop
Most commands of the lsDeejay product line but DJ command itself are ignored on lsDeejay channel. The later has the following form to login and logout a DJ.
[11:21] :lsDeejay server 08113: DJ,2682eb10-ee55-46a6-bc49-0f09a39d152b,Kephra Nurmi [11:21] :lsDeejay server 08113: DJ,00000000-0000-0000-0000-000000000000,
Client Scripts
The following open source scripts could be used to talk to the lsDancemachine:

}
