[rules-users] Drools Java and .Net

[Corneil du Plessis]

We have successfully used IKVM to create a dlls for our Drools application.

The performance was a bit slower on IKVM/.Net as in Sun Java 5.
We dynamically load a large number of rules and found the largest impact 
is to the 'load time'

The performance impact was not such that it would make a network call 
viable; especially with 1000s of clients.

Apart from the performance impact the behaviour is exactly the same.
