Some questions: * why limit the number of matching transactions to 255? * what does "each hash and key in the output script" mean exactly? what about the output script in its entirety? * is sharing parts of the merkle branches not worth it? > Design-wise, it occurred to me as I wrote the BIP that the method of > delaying reception of invs is a bit ad-hoc.

I'm not in favor of stuffing too much into the version message, it already seems overloaded. A byte with some bit-flags is fine by me - higher bits can later be added for other boolean flags. -- Pieter ------------------------------------------------------------------------------ Everyone hates slow websites.
