I wanted to build an optical imaging interferometer that worked over
a phone line.

Why didn't you?

I'm already a two or three years behind schedule on my main project, and
since I don't have my PhD yet, I'd never be able to get anybody to take me
seriously in a grant application. I'm still in the process of thinking it
through, to see if it makes sense to try, and I'll give it a priority bump
if I can get a paper out of my proto-thesis.

Besides, I'm just a humble mathematician, and I really don't know as much
about hardware as I'd like.
