Excuse me, but the FastCGI protocol is *WAY* more complex than
the "mod_lisp" protocol, so much so that it *was* a "barrier"
to me when I was writing my first Lisp-based persistent web
application server. A large part of that complexity is the
packed-binary FastCGI "records" you have to parse and generate,
with a maximum data length of 65535 bytes per record, which
means that long requests/responses have to be broken up into
multiple records [which adds sub-request state management!].

By contrast, the plaintext, line-oriented nature of the "mod_lisp"
protocol is a "no-brainer" for anyone who has ever written a CGI
script. You can even test it by manually typing [well, probably
cut&pasting] into a socket with a "mod_lisp" server on the other
end and watching what comes out. Really.
