Depends, doesn't it? However, if the original object is incompressible, it's simple enough: each of the m blocks must carry additional bookkeeping information to enable the recipient to figure out how to recreate the original. Therefore the aggregate size must exceed the size of that original object. -- Jim Dixon [EMAIL PROTECTED] tel +44 117 982 0786 mobile +44 797 373 7881 http://xlattice.sourceforge.net p2p communications infrastructure _______________________________________________ p2p-hackers mailing list [email protected] http://lists.zooko.com/mailman/listinfo/p2p-hackers
