Speaking of bonding .. what's needed to allow two modem-based PPP interfaces link to the same destination ? As far as I can tell .. i) you need one "virtual interface" at the route socket level with path splitting underneath it. ii) the "splitter" needs to have an intimate knowledge of the transmit queue lengths of each of the paths in order to choose the one with the least latency. iii) Possibly, with assymetric or paths of different speed, some weighting needs to be applied in addition to simple length assessment. What else needs to be addressed ? Can this be (realistically) done by hacking on ijppp or is it a kernel-only job ? Linux seems to have this capability .. do we want (need ?) to be compatible with them ? michael
