What about adaptive tuning?

Have some kind of a "fool" list, wich says how many times the cache pulled
an object from Micro$oft, which hasn't changed, compared to the
number of realy "needed" pull's.

If the cache gets "fooled" 99.9% of the times, then you multiply the
expire with 1000.

Maybe the numbers may need some adjustment....

PS. You need to store a CRC on all objects, otherwise you can't tell if an
    object realy changed :-(
