It would be extremely useful if the routing table could be
a per-process variable which is inherited by child processes.
That way it would be possible, for example, to start Apache
with its own routing table (which would be inherited by CGIs
and other programs exec'ed by Apache).

Another approach would be to assign a routing table to a jail.
However, for me personally, jails are currently not very
useful because they can only have one IP.  That limitation
would have to be lifted first.

I would also like to have better control over the source IP
of outgoing connections.  I often have a lot of IP addresses
configured on an interface which are assigned to different
services (possibly belonging to different customers, i.e.
they need to be accounted separately).  Currently, the only
generic way to force programs to use a certain source IP is
to put them into a jail, but again, I often need multiple
IPs for a service so it doesn't work with jails.  Same
problem as above.

Just my 2 cents (since you asked for it).  :-)

Best regards
   Oliver
