A central "call router" is one reason one might want to use the 
application.  The other is in situations where each call has a "cost" 
associated with it, and simply forwarding a call via a re-INVITE may 
be insufficient to manage how costs are calculated.  Performing a 
re-INVITE may be the only way to make it happen correctly.

I have put a $200 bounty on it and announced it to the -biz list. 
Any takers should contact me off-list, and anyone that wants to 
increase the bounty should reply to the post on that list.  Unless 
there is specific commentary on code implementation, I think this 
conversation should move entirely to -biz at this point.
