With ricochet modems, as far as I know, the "other end" of the ppp
connection is the modem. These devices do not speak ppp over the air,
they use "lightweight ethernet protocol", or something like that (I
forget what it's called). The ppp interface is presented to you by the 
modem itself.

What you want is a feature of linux kernels that allows you to bring up
multiple interfaces and set up multiple defaults routes, one default
route to each interface. Then linux does some sort of per-connection load
balancing, assigning each new connection to an appropriate interface
(it may be as dumb as a round-robin, or it may be more intelligent, dunno).
You probably have to use the 'ip' utility to do this, and I haven't done
it; this info is second hand.
