I happen to have a demo switch onsite right now that claims to do
that, but as you say $$.  I think this one starts at $10,000 and goes
up from there.

Our current phone system uses Cat5 in the walls/ceiling, so
implementing a dedicated Voice Lan Segment would not be that difficult
for me.  Mostly a matter of changing out the connectors on the end of
the wires and putting in a hub in the phone closet.

And setting up the IPtables masquerading logic sounds like a small,
but interesting challenge as well.
