A few points to make here:
1) HTML/CF based app needn't rely on meta-refreshes exactly, but could
rely on _javascript_ (like rob's app). They will still be based on the
HTTP request-response model.
2) you can have CF keep chat data, messages, who's online, etc., in
memory (application variables), in XML files, or whatever storage
mechanism you desire. Databases aren't required for CF to function.
3) Flash and Java based chat apps are better than CF, ASP, PHP, etc.
apps because Flash and Java can make socket connections to a back-end
server. Instead of constant check-ins, they can stay connected while
receiving and sending events from the server asynchronously.
4) You need a socket server, as well as a client. For a flash front-end,
the easiest way is with Flash Communication Server. If you want to be
cheap, I'd recommend Java or a .NET server, but maybe you can find some
other implementation.
4) Blackstone (the next version of CF) may be able to act as a socket
server through a java listener. I greatly look forward to playing with this.
