But hosts is operating system-wide.

Both ipfw and pf support tables, which is what you
want, large sets or unrelated (addresses|networks).
Both of them support UID matching as a target
(caution: this feature is not mpsafe on FreeBSD-6).

Out of curiosity, how big your hosts file is?
Can you share it with the rest of us? Perhaps
upload it somewhere, so we can try your approach?
