Of course. :)  The idea would be to use a cgi::request object, which you
could pass a 'service' object to: the service object deals with the protocol
and then the resulting cgi-shaped request can be transparently accessed
through the request object.

Well I've been having a go implementing the fastcgi protocol using asio and
even though it's not finished, I believe given some dedicated time I could
have it fully working. SCGI is supposed to be 'simple' - and seems to be -
so that shouldn't be too big a deal to add: either way, that is something
that could follow, I suppose? Then there's the docs of course. Forgoing any
major oversight on my part, from what I understand so far, I think it is
doable in 2-3 months.

It probably isn't, although I honestly don't know. Thankfully it won't
really matter since servers should be able to run fastcgi apps via tcp
anyway (apache and lighttpd do). Using UDS/pipes is purely an optimisation.
