Why don't ISPs peer with everyone?

Peering costs money. The transit bandwidth saved by peering with another
network may not be sufficient to cover the cost of installing and
maintaining whatever connections are necessary to peer. Then there's the
big networks who really don't want to peer with anyone other than
similarly sized big networks...everyone else should be their transit
customer.
I manage a network that's primarily a hosting network. There's a similar
hosting network at the other end of the building. We both have multiple
gigs of transit. We don't peer with each other. Perhaps we should,
because the cost of the connection would be negligible (I think we already
have multiple fiber pairs between our suites), but looking at my sampled
netflow data, I'm guessing we average about 100kbit/s or less traffic in
each direction between us. At that low a level, is it even worth the time
and trouble to coordinate setting up a peering connection, much less
tying up a gigE port at each end?
Anyone from hostdime reading this? :)
If so, what are your thoughts?
