If performance were an issue, I''d benchmark it as is, then test it
using a find_by_sql. So far, performance hasn''t been an issue for me.
I''d also have to figure out how to go about initializing models with
the values pulled from that find_by_sql. Premature optimization, and
all that.

MIchael Koziarski brings up an interesting point, however, and I''m
interested in hearing discussion on that as well.
