I'm looking into using a flash (xmlsockets) gateway to implement low latency connections between the browser and the server (Aolserver), in short, an implementation of COMET using a flash component.
I must admit that creating a socket server in AOLserver is not as straightforward as say in Apache with PHP or CGI perl but my research has led me to a number of different (possibly unrelated but potentially usefull) things.
Memcached : Someone has written a tcl api to memcached. Memcached caches db requests for clusters of AOLservers. It can run as a daemon on an unused server and allow several clustered web servers to share a cache of db requests. I was particularly intrigued that LiveJournal .com uses it with positive results. Dave suggests that it would be neat if this could be augmented into ns_cache.
Naviserver : I've known for sometime that there is a fork of AOLServer. I just noticed that they have lots of potentially useful modules. Some of these are familiar AOLServer modules. I would be interested to find out if any of these modules will work on AOLServer 4.0.10 and 4.5. Another intriguing question is whether OpenACS can run on NAVISERVER.
OpenACS works fine with NaviServer.
