We all hope for that to happen ;-)

An issue here is that there's a wide gap between what the market offers in terms of SIP device functionality and the IETF's vision. At some point, I wish that the SIP forum copies  the work of the XMPP Software Foundation and tries to define standard SIP profiles for their members, so we can move the market forward in terms of implementations. SIPit events really help here as a means to educate SIP developers and put some peer pressure on them.

Sorry for being a bit off topic. Favorite topic, I guess ;-)
