I realize that Webex does not support Ubuntu 11, however I have a website running on my machine that I need to demo for a client and he will use webex. I need to be able to use the "share desktop" feature to do this. Is there any dependable way (gksudo, java installation, browser, anything) that lets you share your desktop?

I don't care if the audio crashes since we talk on the phone, and it's okay if it cuts out from time to time -- I just need him to be able to see it.

Alternatively, is there an easy way for me to switch to an ubuntu version that will allow me to share my desktop?
