If you're willing to play DNS tricks, it may not be so hard to make pool.ntp.org resolve cleverly to a host appropriate to the requesting client. Companies like Akamai have been using DNS to send you to a "nearby" server for years. The cost is that you need more serious DNS serving infrastructure, since you lose a lot of caching.
I'm not sure how exactly Akamais version is implemented, but I suspect they have a BGP feed (or something equivalent) to each of their servers and thus from that can build a map their DNS servers can use to give you a topologically nearby server.
We can't do that with the kind of servers we have in the pool, but we can (with relative ease) make pool.ntp.org return "nearby" servers. (Of course the usual problems assigning "nearby" applies).
