The district 4 director of BART actually came by old sudo room and Matt and
myself sat down with him for a while. I talked to him again about the mesh
at the Temescal street fair this past July and he said he'd introduce us to
the person responsible for the BART fiber when we were ready. Here's his
info:

I might have his private number somewhere in case you can't reach him on
that number.

That idea sounds like it has potential, though we're not really getting 100
mbps (might be partially due to our in-house wiring) and especially not
upstream. Finding people who are super close to the dslams and have tall
rooftops might work though.
