The 300 IDB limit thing hasn't been fixed for quite a while. It's really
memory and IOS-level dependent right now. If you max out the memory on the
2600, you should easily get beyond that in interfaces. I've got about 500
running on a 3620 between VLANs and Frame sub-interfaces on one clients'
router. There's a "show idb" hidden command, but unfortunately, I don't
know any way of finding out the maximum for your configuration.

I believe that you are going to hit the max IDB limit on the 2600
at 300 total interfaces (including subinterfaces).

I haven't seen any significant impact in router performance by simply
using dot1q or ISL subif's. I don't know much about the physical FE
on the 2600's and how well it will operate as a "router on a stick"
as in, how well it performs in full-duplex capacity.
