Q:

Alternatives to BizTalk as a rules engine

My customer wants a end-user configurable rules engine. Currently they are considering BizTalk. Are their any other alternatives that they should consider?

A:

InRule makes an interesting looking rules engine, but I have no idea on the price: http://www.inrule.com/
