To be honest, I don't have that much to offer; but I know what it's
like when one posts to the list and gets no feedback at all, so here
goes ...

I don't know.  Currently whenever I want to add a Web interface to
a program, I just knock up the HTTP server infrastructure as part of
that program.  But perhaps that's silly - would advantages would I get
from using mod_lisp instead?

I don't understand what the mod_lisp protocol is, so can't really
comment.  I'm interested in the architecture though - can you describe
it (or point me to reference)?

How would that help?  (Genuine question.)

> * How bad is the user-interface?

Do you mean the programming interface?  (By UI I'd normally understand
something like a window or a command line, and AFAICS mod_lisp doesn't
have either of these.)

Don't understand enough yet to know!  Please explain further.

Presumably you mean a SRFI defining a common Scheme API that people
could use to write code that plugs into your mod_lisp engine?  (I
guess I'm missing the architecture again here.)
