Possible issue with desktop sharing and tunnelling

[bigbluebutton-issue-import]

Originally reported on Google Code with ID 1582

Received the Java console output from a person who said desktop sharing worked from
them in 0.80, but not in 0.81-beta (demo.bigbluebutton.org).  

I think it's a firewall issue on their as I was able to share desktop to their server.
 However, as they were able to connect and launch BigBlueButton, they should have also
been able to launch desktop sharing.  

See attached log.

Fred, can you let me know the other person and I can test here - we have XP, 7, Linux
and Macs that we can test and replicate on if you need.
