Whoa. Just what protocols are these? And why is the web at all 
relevant in their light?

I guess it come down to this: people here and there take issue with 
the capabilities of the web from time to time along these lines - 
'it's not good for X, X is important, therefore the web needs to be 
improved for X', where X transactions/security/sessions/reliability 
and whatnot.

If these said protocols are optimal for a job, why is this group not 
called the protocol/abstract architecture group, and why is the web 
of any interest if we have such protocols?

I'm not being flippant; these are questions that customers ask me 
about web services. I have an intuition that it comes down to 
protocol gateways and uniformity, but I don't know that anyone's 
actually said that.
