Some of the changes in 0.5 :
•Java3d -> jMonkeyEngine•MTGame multi-threading engine•Module system allowing for extensions to the virtual world in a clean manner•Automatic deployment control via JNLP / modular builds •Web-based administrative interface•More robust experience

Features we didn’t need to make in 0.5:
•Enhanced avatar customization•Real-time security module

The unspoken killer app: Desktop Sharing
•What is desktop sharing?•In 0.4 we built LifeShare, a standalone program to allow for desktop sharing•Complex system involving VNC server, VNC->RDP bridge (via xrdp ported to Windows) and RDP clients•Maintenance was difficult and it did not integrate well•With 0.5 we had to start over
![Page 9: Status Report Sponsor: Rockwell Collins and Emerging Media Initiative Ben Johnston Wayne Zage Dolores Zage](https://reader035.vdocuments.site/reader035/viewer/2022070412/56649e545503460f94b4b310/html5/thumbnails/9.jpg)
The new LifeShare:
•Embedded VNC server to share to the X11 App Share•Built-in proxies for network configuration and security concerns•Wonderland’s Sun Application Sharing engine, to display and allow interaction in-world•Custom plug-in to handle communication and synchronization issues

Future Steps:
•Finish work on Lifeshare including proper shutdown hooks and proxies•User testing for usability and performance concerns•Future funding?
