Run BIRD without binding to a local TCP socket?

Is it possible to run BIRD in a speaker-only only mode, such that it does not bind to a local TCP socket, for the BGP protocol? While i can bind BIRD to different TCP ports at start-up, many vendors do not support specifying a destination port other than tcp/179. I'd like to run multiple instances of BIRD on a single server, each instance peering with 1-4 peers. The goal is to distribute BIRD across multiple cores, improving the number of queries per second to BIRD's control socket. I apologize if this has already been discussed, but an initial search of the archives did not yield a similar request. -- Eric Cables
