Hi Jon,
You could do this rather easily if you get a Point-to-Point
T1 between the 2 buildings, you'd actually set one of the routers to
act as a frame-relay switch (dce) device, and then create sub-interfaces
for each bridge group.
This is probaby the easiest way to accomplish what you're looking to do.

Host router:
int serial 0/0
encap frame-relay
frame-relay intf-type dce
int serial 0/0.1
frame-relay interface-dlci 1
bridge-group 1
int serial 0/0.2
frame-relay interface-dlci 2
bridge-group 2
.
.
.
Remote router
int serial 0/0
encap frame-relay
int serial 0/0.1
frame-relay interface-dlci 1
bridge-group 1
