I think that applications that are multicast aware are supposed to
figure out which interfaces that they want to bind to anyway, so they
should not be confused by the multiple routes.

Yes, it does need swap if you intend to run gcc.
I suggest that you might want to try the UML image system in the
Openswan builds. It generates everything you need. It has been used with
2.6.9+ guests, on 2.4 and 2.6
