->divvy up your packets between the two PPP lines?  You could pretty easily
->spew packets out to two different destinations over two interfaces, but
->what you'd really like to do is alternate the interfaces, and that's hard.

I experienced a pretty good performance enhancement by using two 
ppp-interfaces with same addresses and getting my provider sending packets out 
to one interface while I sent my packets through the other line.  Worked like 
a charm, although not as speedy as one would have expected for 2x14.4.  

That was back in the old days befor ISDN reached my home ;-)
