Greetings,

It’s very cool to hear you guys are interested in separate routing.

Running multiple routing daemons isn’t too much of a problem though.  The
memory size isn’t usually very high, and it is more likely to be secure if
the daemons are separate.  If somebody was going to run a large instance of
routing they should probably use a router, not a unix box.
