A panel discussion with team members from IMA including progress on EchoVoice and OSFest 2022-2023 Postmortem. This is a panel discussion on cultivating, collaborating, and celebrating the Hypergrid community as contributors, hosts, and sponsors of OSFest2023 and innovating with a technology focus on community needs and various use-cases. Technical aspects include: filling gaps in grid/platform development; supporting the OpenSimulator-NGC Trusted Grid initiative; reviewing progress on EchoVoice; and presenting a postmortem on OSFest2022-2023. The work of IMA is in general directed toward broadening the use of virtual worlds for Public, Education, Industry, and Government sectors, but the community as a whole benefits from open-source efforts.

10. DESIGN ASPECTS
• Choose intermediate interfaces

11. DESIGN AND ARCHITECTURE
• Components
• Region Module
• Bridge Server
• Mumble
• Bridge Client
• Viewer interface
Implemented in this step

12. IMPLEMENTATION
• Region Module (1700 LOC) provides:
• User information
• Region and Grid information for
Channel definition
• Bridge server (1200 LOC) provides:
• Self compiling OpenSSL,
• HTTPS interface for Region module,
• Processing unit parses the HTTP
request
• Channel hierarchy management
module parses the given region
object to murmur channels
• User move module
• Register users
• Hashing user ID
• Moving users
• Murmur interface
• Interfacing with Murmur server

13. NEXT STEPS
• Finish Server Bridge
• The user move module needs to be completed with the move
part of the module
• Test the whole configuration with OPENSIM & MURMUR +
Server Bridge on different servers using a mumble client
• Start developing the client bridge.

27. IP CONCERNS:
Intellectual Property and Copyright Law
• USA: Title II of the Digital Millennium Copyright Act (OCILLA)
• Other Countries: Most have similar law and offer reciprocity with the USA
Grid Owners must meet all specific requirements for safe harbor protections
• Must remove alleged stolen material
• Must follow policy for terminating/banning users who are repeat infringers
• Must accommodate and not interfere with standard technological measures to protect IP rights
Contributory infringement can be imposed on a grid owner if they fail to meet all requirements for safe harbor
