The hack i submitted to mpd was to make it so that mpd simply alternates sending packets between the two modems, however, I definitely did see a good performance improvement over a single modem with the 2 couriers I was using. I don't know if the hack will work with PM3s...I don't see any reason why it wouldn't, but I have never tested it. > If mpd works with Livingston PM2 POTS, I'll probably bail on the old > FreeBSD box I installed there to use as my endpoint for mpd -- might > save me some complexity and trouble.

Would you still > recommend it or is user-land PPP up to snuff for multi-link/line? I prefered mpd over ppp several months ago, but I don't know what changes have been made to ppp since then. I never bothered to check anything else out.
