Just out of curiosity, what is the biggest source of the delay from
switching to 1.5.2?  Is it a matter of "if it ain't broke...", or do the
changes warrant enough work (rewriting code, updatin libraries,
etc.) that it is a big job?  I'm writing apps, and currently rely on
some 1.5.2 behaviors, so I'm curious as to how difficult it may be
for customers to upgrade if need be.
