Ok, so SIP is nowhere near useless. It is being used all over the place and will eventually replace H.323. Telcos like Vonage (which uses Cisco SIP equipment), deltathree, and Denwa are using it for last mile telephony connectivity for residences and enterprises, and WorldCom, after surfacing from its financial issues, will be using it on its global network as well. Microsoft has built a SIP client into Windows XP (Microsoft Messenger) and SIP is very flexible and extensible and the best place to start is http://www.sipcenter.com. PBX manufacturers like Mitel and Siemens have developed their PBX completely around SIP.
To get back to Cisco (as this is a Cisco newsgroup), Cisco has taken the time and $$ to start to develop SIP functionality in its products despite the fact that it isn't need for AVVID at all. Though their initial SIP focus is on carrier-class products (since that is the logical choice -- see my list of companies above), my bet is that SIP will surface as a more central part of the AVVID architecture for the enterprise.
