Rete-based system are as fast as possible, but don't guarantee
response within a specific time frame. Since "near realtime" is a
fuzzy concept, you can just try it and see.

Well, of course!

Jess is constantly evolving, but I always have a stable 'release'
version available separate from any experimental versions. I'm it as
far as a support organization goes, but there are companies that will,
I believe, sell you support, consulting and training services for Jess
(see the "links" page on the web site.)

Jess uses a rule language based on CLIPS. You have access to all Java
APIs from the rule language.

Jess' license fee is negotiable. A license is required for offshore
commercial use.
