Watch out if you use X-Lite on the Mac and you're thinking of upgrading to OS X Leopard.
It breaks X-Lite. It broke eyeBeam also, but Counterpath have released a patch for that (go to the Counterpath site and grab the latest version).
A fix for X-Lite (3) is a few weeks away. More information on the Counterpath forum:-
