It seems really interesting. Just a question please:

I've tryed the following scenario:

   alice at domain_A --UDP--> proxy_A --UDP--> Proxy_B --TCP--> bob at domain_B

Dialog module shows the following route set for the caller:

caller_route_set::
<sip:proxy_A_IP;transport=tcp;r2=on;lr=on;did=2bf.1ed4b0a5>,<sip:proxy_A_IP;r2=on;lr=on;did=2bf.1ed4b0a5>

How would be matched this route set? as string comparission? (I hope no)
Would important parameters as "transport" be matched?
