I am a huge IOS bigot (on a diet).
But I would probably allow that IOS and gated might be even on BGP features.
Now, the set of features and how they're distributed throughout the protocol
is different.  Gated has some underlying added flexibility, while Cisco has
some added knobs on most things.

You can control redistribution by tagging things or by looking at AS-Paths
w/ IOS.

Does it have AS-Path padding?  I know some (hi Peter) think it's evil,
but many use it...
