RE: HSRP availability in datacenters?

We currently offer HSRP everywhere, the problem is that it doesn't scale on
a budget. For example, a 3550 can do 16 HSRP groups, limiting the number of
customers that we can attach to (2x 3550s) to 16. That's a lot of
distribution infrastructure for 16 customers. Then to scale that, say, to
200+ customers, that means we have 12-13 pairs of distribution routers, each
with 2x gigE uplinks to the core ... Which means that either (A) the core
has to be really big or (b) we get fewer, more powerful distribution
devices.

This is where my employer is at now - I admit, we're tiny in the datacenter
world - but the cost to aggregate 100+ HSRP groups into the core, with room
to grow, is pretty staggering for a smb. 

This why the suits are wondering if there is a revenue opportunity hiding
somewhere to finance such a thing. Ah, the joys of growing out of your
britches :)

Thanks for any continued response,
Randal
