If you start pppd with the "demand" and "idle (seconds)" options, it
will fire up the connection whenever there's traffic, and hang-up the
line when there's no traffic for the specified period. If you have the
right kernel options, you can even use "active-filter" to prevent
certain types of traffic from bringing up the connection or holding it
open. E.g.: "active-filter 'not udp port ntp and not tcp port imap2'".

It's easy enough to bring up two ppp connections, if you make only one
have the defaultroute option. For the other, you could add a route
manually to a news server or something. If you expect to simply double
your throughput transparently, I don't know that it's possible to do that.
