Oh, and I completely forgot: IIUC you have to unpack the (possibly big) 
delta-chain until you have the delta you really want, right? So, you might 
want to have a clever mechanism to keep the delta-chains short for recent 
objects (i.e. objects you are likely to need more often).

At least, the delta-chains should be limited by size (_not_ by number of 
deltas: you can have huge deltas, and if you have to unpack 5 huge deltas 
before getting to the huge delta you really need, it takes really long).

Ciao,
Dscho
