Does anyone know where I can find out of the box desktop
sharing software? I looked on Tucows and download.cnet.com
but all I found were the usual suspects offering free trial or limited
use apps.

I want to host my own, not use someone else's. I do a lot
of training and presentations and I'd like to be able to send
them to my site instead someplace like GoToMeeting or Yugma.

If you're a programmer I've posted a request for proposals in
"looking to hire" forum.

Thanks!
