Perhaps it's not later bound, but it's very different stuff.  The stuff
posted from a form is just nouns, and the handlers in the CGI script are
there to accept the nouns.  The stuff posted from a Web Service is a mix
of nouns and verbs, and it generally seems to me that bindings about
verbs are more nastily complicating than binding to nouns, whenever it
happens to take place.  

So long as CGI is about handling nouns inside the HTTP contract, I think
Bill is right that:

>>[CGI] has nothing to do with the Web's client/server contract.

Then again, I've argued more than once that REST has too many verbs, and
that passing nouns from place to place should be enough.
