Like others, i did my litle framework who can work on top of twisted,
cgi or BaseHTTPServer. So it's possible ;-)
But it doesn't mean that i whant to run my application on any
server. Generaly i use twisted server when i have specials need, like
telnet, irc... So this application will not run under cgi. But i like
to can reuse quickly somes litle cgi application under twisted.
I need the same framework for all the servers to can share 90% of my
api, to map the url to a resource, for session, cookies...

So, i hope we can find a solution to run simple application anywhere,
and to be open for very specific uses.

Sorry, because of my poor english, i cannot help a lot in the
discussion...
