Timed caching would be great, and would make the whole
process faster.

Sure, go ahead :)
But remember, this is a 10 min hack - I've done the
minimum work needed to 
scratch my personal itch, so I could finish the first
version of my program and move on to more pressing
matters.
A global timed caching system would do the same work
with a more, well, global effect.
Until such a system is installed (I think I'll look
into that on my spare time...) this would probably do
the trick.

Thanks again,
Ido.
