Then you'll have to tell each machine individually how to reach the other
network.  "route add -net gw metric 1", for example.

So, the IP addresses in network 2 will have to be public, or you'll
have to set up the linux router to masquerade connections from network2
to the public internet (but probably not to the other local network).

This should work fine.

It's really your only bet unless you can modify the current routers.
You'd need to modify routers 2 and 3 most likely.  It's hard to tell
without knowing all the specifics (IP addresses of all parties

It's definitely doable though.  Sticking with static routes on the
machines in question is easy enough.
