Been there, done that technique... unfortunately it can't be used to
dynamically load script that will be "seen" by the currently executing
scope... this isn't quite true... I think one browser saw it right off,
another saw it if I used eval on the retrieved source, but other
browsers don't see it until after the scope (function scope) exits. The
exact semantics are quite varying which provides for completely
unreliable loading of dyanamic script -- and to be frank I try to make
my stuff work with IE/FF/Opera. I could care less about NN4 in this day
and age :)
Cheers,
Rob.
