If you are running Ubuntu 8.XX,
install wine from the wine repos (add them to your software sources)
install winetricks from the link off winehq
install IE6 via winetricks(necessary for accepting their eula/tos)
install Crossloop via their executable.
and thats it, it should work out of the box.
at the moment you can only remote others' desktops, not share yours.
to share a linux desktop you use ssh with a reverse tunnel and vnc server on your end..
ssh -R 5900:127.0.0.1:59000 -p 22 username@their-ip-addr.
they then point their vnc viewer to 127.0.0.1:59000 and log in with the password for your local vnc server.
