    It's actually possible for there to be multiple Path headers. They may also 
be accumulated and be separated by ","


I have some general design comments which I think could improve things a bit:

1. I think it's time we make the contact object a parameter to request creation 
and session creation. In my mind as things continue to be added there's going 
to be additional information associated with it which may influence the 
creation process, and it also makes the next thing possible.

2. Make the contact available to outgoing request supplements. This would 
greatly simplify your supplement and could be useful further down the road for 
other things. One way of accomplishing this would be to store it with ref 
bumped on the tdata mod_data, and then after all the supplements have been 
invoked to simply drop the ref. It doesn't need to persist for the lifetime of 
tdata (and since it wouldn't it would need to be documented as such).
