i'm not smart enough to know the difference between CGI and WSGI, but i have inserted custom WSGI middleware on GAE before web2py successfully. (perhaps because web2py is using CGI it was harder than i expected)
i am interested in 2.7 and concurrent requests, though i don't know how to audit my code to know that it is safe for concurrent requests and i have not signed up for the 2.7 preview (and am still waiting for a SQL invite for GAE) all on my TODO list...
