By that you mean that ppp shouldn't add > default routes to the gateways? Oh, no. By that I mean that the ip-up.local script should set the route itself, depending on whether there are one or two ppp links up already.

You should add gateways for the different outgoing devices and set up host routes to those gateways specifying as the preferred source address the address associated with the interface through which you route to the gateway. Further, adding rulesets to deal with the case that packets already have a source address set might greatly improve reliability. There's some information on how to do that in some previous mails I made to the list.
