ok, so they didn't do the community at vlan hack then.  Not unexpected.  looks
there might be three separate cases to consider here then:

1. single instance BRIDGE-MIB
2. multi instance BRIDGE-MIB
3. P-BRIDGE-MIB

option 1 is supported by all the kit we currently use (NI-CES2K, TIX24, and
some management switches - C3500XL, netgear GSM7224).

option 2 is supported by some other kit (e.g. netgear), but not on the
brocade kit or the old cisco kit.  Not going to implement at the moment
because the perl snmp library I'm using will probably not support it.

option 3 is supported by the brocade + netgear kit, but not the C3500XL.
apparently also juniper + F10.

I will take a look at this tomorrow and see what I can come up with.
