Greetings, 

It=E2=80=99s very cool to hear you guys are interested in separate routin=
g.

Running multiple routing daemons isn=E2=80=99t too much of a problem thou=
gh.  The 
memory size isn=E2=80=99t 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.
