did you check the add_procs callbacks ? (e.g. mca_btl_tcp_add_procs() for the tcp btl) this is where the reachable bitmap is set, and I guess this is what you are looking for.
keep in mind that if several btl can be used, the one with the higher exclusivity is used (e.g. tcp is never used if openib is available) you can simply force your btl and self, and the ob1 pml, so you do not have to worry about other btl exclusivity.
