Yes, thanks!  I saw those when I was researching Twisted - David Mertz
sometimes posts to c.l.python, and he mentioned them.

I've written most of a non-trivial app in Woven, and it does some very
nice things.  Unfortunately, 'under the hood' it is rather crufty, and
their MVC doesn't seem to work quite the way we needed, so we've moved
on.

One of the Twisted principal developers is now working independently on
Nevow (Woven spelled backwards), which is essentially a rewrite using
what was learned from Woven.

I've never used Smalltalk, but I did find this interesting:

Scheme-style continuations for session logic/flow control - I'm not sure
what happens when someone presses the 'back' button in their browser,
though - I wonder if continuations can go backwards? ;-)

Was the ACE article one of these, by any chance?

http://www.cs.wustl.edu/~schmidt/patterns-ace.html

CMUCL and SBCL have an async interface called SERVE-EVENTS - I need to
see how suitable/general it is since I think there is at least one web
server (Araneida, IIRC) that uses it - but I prefer to use GCL.

Whether or not SERVE-EVENTS turns out to be suitable, my hope at present
is to start with something like Python's asyncore, add support for the
Reactor pattern (e.g., event handler functions, see the patterns-ace
URL) and use that to structure networking logic.

Nothing to it, right? ;-)

Aloha,
