The big win is bought by having _one_ zlib stream for multiple deltas, right? So, everytime you want to access the _last_ delta in the chain, you unpack _all_ of them. This quite obvious conclusion is obviously your reason to propose two packs, one for the archive of "old" objects, and one for the "new" objects. > As for public servers there is an immediate win in shifting to the new > pack format.

Have you thought about a non-upgraded client? The server has to repack in that case, and if the client wants a clone, you might not even have the time to kiss your server good-bye before it goes belly up. There is an obvious choice here as to how fast people would upgrade their servers.
