For about $6k all in, you could pickup a monster dual Xeon server with a few
10GE PCI line cards and run a subscription service of the Vyatta open source
router.  With high end machine specs, we've been able to run 5 full tables
and a solid amount of peers with about 6.5Gbps sustained to the net without
any stress.  For  access, we just trunk one of the PCI cards down to a 6506
or a 3750 and it runs nice and clean.  The only downside to this setup is
the lack of cisco proprietary software features which it sounds like you
might need.  If anything you might be able to keep your existing setup and
uplink everything to one of these routers as an edge device.
