diffdrive with multiple roboclaws?

[davidf-2013]

not sure if its an "issue", mostly a feature query to figure out if i'm looking for a feature that
doesn't exist yet, or doing something wrong..

can you use the diffdrive with multiple roboclaws?

i have a 4wd robot with two roboclaws. both roboclaws are connected to the same uart on a raspberry pi,
one is 128, one 129, using packet serial multiple mode..

the diffdrive node works great with the robot controls in rviz, but only for one set of wheels, even when i upped
"roboclaws" to 2.. also i subbed in roboclaw_multi for roboclaw_single in the launch file..
thanks in advance! (and for making this no-nonsense driver..)
