The multilink stuff is still under development and this kind of thing
is the part that still needs to be sorted properly. I'm surprised
that you got multilink to work at all with a pppd as old as 2.3.10.
2.4.0b4 is the current development version.

Not quite, it should be splitting traffic in both directions. At the
moment the first pppd controls both that link and the bundle, so if
you kill it you lose the lot, not just that link. As I said, that's
something that needs fixing.

I wouldn't say it's really ready to give to a customer yet unless they
are pretty adventurous. :-)
