And the good nwews is: all the infrastructure seems to be in place, the
connection info passed to the kernel module already needs and has both
local and remote addresses, looks like it's really just missing the bind
call in drbd_receiver.c
Patch against 0.7.11; Warning: not tested yet beyond the fact that it
actually compiles :-)
