I haven't looked at it in detail, but yes, I think it'd be technically
possible to do this, at least *within* a process. Of course, you'd
run right into the problem that multiple HTTP processes are typically
started and the data couldn't be shared among them. There are also a
lot of limitations for this kind of library on UNIX, like you can't do
anything that would result in delayed execution such as "send in" or
asynchronous open/read/write socket.

The DLL interface to IIS is similar enough to Apache mods that it
should work the same way. Of course, we're not considering doing
either of these things because it'd be a lot of work and you'd end up
with something less useful than just writing a little client/server
system and running MetaCard as a separate server, or just using mchttp
instead of or in addition to another HTTP server.
