tor could easily be made to efficiently use a similar mechanism, if it doesn't already in order to perform the lookups to compute the answer to "What is the subset of exit nodes allowing exit to IP addr X on port Y?"
The answer may lie with the client polling some exits and computing the answer to its needs locally. I just posted a blurb about this to tor-dev. Anyone interested may want to follow up and add on over there.
