• If we're not coming up with something new and innovative we're stuck making outlook clones. People don't like writing software like that.

What are you talking about?? Writing clones of commercial software is the prime directive of open source! I'm going to go out on a limb and say that actually there are quite a lot of people who like nothing more than doing exactly that.

Rohan Mahy (co-chair IETF SIP and SIPPING Working Groups) said:

"As with anybody who has technical problems with IETF protocols, I invite them to write a description of what problem they are trying to solve which they feel is not addressed by existing protocols and provide some motivation. Zennstrom has not provided any rigorous analysis or even detailed explanation of these alleged technical problems.

"The traditional telecom folks want to reproduce an environment which is familiar to them. SIP does things differently, but many folks generally stop there and don't try very hard to understand how to accomplish their goals 'the-SIP-way'.

"I believe that Zennstrom has a different motivation. He is providing a packaged service and I believe that he is afraid of the idea of open services and open protocols, because these things directly threaten his business model."

But yeah, a SIP/IAX gateway to Skype would be very nice.
