Same spacing as QFP, which I've done successfully.  I didn't try to
toner-transfer it, though!

I did have my soldermask ganged by the manufacturer but I was still
able to put down a 208 pin QFP without bridges, just using lots of
flux.  I'm not sure how a home-etch board would fare.

FT232R would be easier to put down, I think.
