This is *not* a recommendation to drop gated, but you may want to
start looking at zebra ( which is becoming stable
enough to use in a "real" environment. Comparing to the public
versions of gated, it uses less memory and less CPU and supported lots
more "new" (read necessary) attributes.

Our external router (just onefor now - it is only a small network)
runs gated, but next time I am back in the office on a weekend it is
likely to get zebra installed. I have zebra operating (bgpd actually -
not kernel updates) on my test/desktop machine with 3 full-ish BGP peers
in 64M RAM:

(IP and ASes blurred to protect my testing partners). This is no
exports - import only, but export works OK in our smaller tests.

The only major area I think needs lots of work is logging - I can
say this because I volunteered to do it, but have not had any spare
time in the passed couple of months.
