One of my colleagues tells me the database-internal (so: postgresql+postgis and so) calculations are lightning fast. Indexes optimized for it. So if you can keep the calculation inside the DB it ought to be fast enough.

I agree however that it's best not to have to work around this issue. So your fix-it-with-javascript idea might be best.
