> 1) Yes kris is still working on the decision stuff for ruleflow.

Some of the stuff is already partially implemented, but an (X)OR split (where you can define which path(s) to follow based on some conditions) is still on the TODO list.

> 3) The Eclipse GUI ruleflow builder doesn't seem to allow loops in the flow.

It does support the creation of loops: create an XOR split as the starting point of your loop, you can then always create nodes that link back to this starting point, resulting in a loop.  Note that looping kind of depends on the (X)OR split as well, as that would allow you to exit the loop in specific conditions (now you will probably create an endless loop).  I hope I'll be able to add that piece of functionality pretty soon to trunk.
