GnomeMeeting 1.2 and Skype

We are again coding hard on the future 1.2 release of GnomeMeeting. There will be more internal changes than user-visible changes, but we are paving the way for SIP.
People are often asking me what I think of Skype. What I think is pretty clear...
The main problem is not that the program is not Open Source, the problem is that Skype is locking users into a proprietary protocol. Would you imagine the Internet with a proprietary equivalent to the HTTP protocol that only a given client could browse? That's what happens with Skype. Skype also has a great marketing force, some people even think that Skype has a superior audio quality. How could Skype have a superior quality when it is using the same codec (iLBC) than software like GnomeMeeting while introducing more latency by making calls go through a 3rd party? The only real advantage of Skype is that it is easily going through any type of NAT, using a 3rd user to proxy the call. But the day when the Linux kernel NAT will natively support H.323 or SIP, Skype will have lost its only advantage... Skype is hype...
