Having recently been through the startup process at an independent
non-profit IXP, I can see spending too much on hardware being a problem
particularly on supporting the ongoing hardware/software maintenance on the
switch. Something else to think about, if an exchange is given an endowment
from from outside entity it might be harder to build the commitment levels
of participants/volunteers because it's too easy to solve the problems with
money as opposed to member contributions.

We went through 3 switch upgrades in 2 years and IMHO it built a lot of
community.

Each IXP will have a set of faithful founders and the key is growing that
group beyond the initial group before the founders lose interest and move
on to bigger things. Particularly before connecting to the IXP makes
business sense to a company that won't connect just because it's cool.

When the exchange gets over the hump were companies are saving real money
it is much easier to keep the ball rolling and the exchange growing. Many
exchange points never make it to that level.
