Region feature requirements

(Off the top of my head) Here are some features which individual sims may or may not support. We should decide on which features a compliant sim MUST support, and which it MAY support.

• Physics
• Portals
• Building
• Crossings (from other arbitrary sims)
• Estate management
• Money (Lindens, private currency?)
• Chat
• Voice
• Instant Messaging, Intra-Sim
• Instant Messaging, Inter-Sim
• Various avatar attributes, such as prim attachments
• Scripting (LSL, mono?, etc)
• Asset relay (local serving of textures, etc vs pointing elsewhere)
• Access restriction
• Centralized logging (dwell, performance)

Please add your own ideas, and feel free to rearrange this list.
