[racket] Racket VM in FPGAs

No problem, glad to have referred you to the paper, I hope it'll be useful.  Just for everybody else on the list, the paper URL is http://dspace.mit.edu/handle/1721.1/6334

If it requires an expensive toolchain, it's still a good project, but much harder for other people to build on after you are done.  (The beefier FPGAs I was looking at in the last year, for numeric computing, seemed to require expensive proprietary toolchains.)
