I vote that the nodes can do that weighting towards smaller keys.
My idea is to calculate the modified LRU:
LRU_mod(key) := m(keySize) * LRU(key).
Where m(.) is defined by a function or by a table like for example:
keySize | m(keySize)
--------+-----------
1k | 1.000
2k | 0.999
4k | 0.997
: | :
: | :
256M | 0.850
512M | 0.840
1G+| 0.820
Advantage: I (as a node owner) can place a little emphasis on "content"
(html, txt, images, freesites, ...) and delete "warez" ;) (isos, DVD-
rips, music) a little bit sooner than usual.
