Adam -
While I might agree with your conclusion, "slightly" better is probably
not the case. Prebuilt images can be quite a bit faster and can also be
of better quality, since any resampling can be done slowly and well.
In the first release of TopoZone, the "map server" that delivered the
pre-built tiles was six lines of code!

I've got to put my two cents of disagreement in on this one. Ask your
users if they'll accept limiting their maps to a dozen pre-set scales in
exchange for slightly better performance. I wouldn't.
Cheers,
Adam
