That's the source of my caution.  I'd much rather keep HTTP stateless  
than to have to deal with poorly designed, limited statefulness in  
the protocol.  And I've been very vocal in defending the stateless  
purity of HTTP on this list.
But at the same time, we're seeing a proliferation of stateful helper  
applications and protocols, with lots of overlap and duplication.   
The result is that none of these systems is widely used enough to be  
compelling for most users to install (or for popular clients to  
support them directly).  That's not an issue in the kind of  
commercial niche you describe (for which a specialized application is  
probably better anyway).  Nevertheless, I feel that there is a broad,  
common need that could be better filled by some standard than by the  
current cacophony of local hacks.
W3C has identified this as an target area of work and, once they get  
the ball rolling I trust them to do a good combination of design,  
testing, and feedback.  (I have no intention of even considering  
CCI++ as a contender in this regard, at least until its designers  
come clean on their proprietary intentions.  Can you say "Unisys"?)
