"MMOX is an effort to collect best practices and develop consensus based standards for virtual world and MMO interoperability. The mmox@ietf.org mailing list is for technical discussions related to this objective and for coordinating administrative details of upcoming meetings." -- IETF MMOX listinfo
This page is intended as a useful container for gathering together links to MMOX resources.
Please expand it with other relevant links that could be helpful. (Don't lose any links. :P)
MMOX mailing list and other communications
Please note that all communications performed under the aegis of an IETF workgroup (this includes IETF email and Jabber) are logged and are permanently visible to the public. They are also considered "IETF Contributions", and as such are subject to the IETF rules on IPR Disclosure. Please read the relevant documents in the IETF Information section below to know what this means.

Requirements tracking
- Unifying object execution models -- requirement to support both local and remote execution models
- Exposing regions -- requirement that exposing implementation of regions not be mandatory
- Avatar diversity -- requirement for transport of avatar visual information between virtual worlds
- Hierarchical objects -- mentioned in passing in MMOX, needs a formal requirement expressed
- A Mission Statement for the IETF -- requirement for scalability, wide deployment, interoperation
- Interop Metrics and MMOX Goals -- quantifying the interoperability requirement as a metric
- Trust Agreements vs Secure Data Transfer, prev -- replacing security theater by actual security
- Decoupling Asset Storage -- asset storage/inventory needs to reflect the diverse origins of objects
- Basic region requirement to support portals -- this also allows user-defined region adjacency
