Just replying to this one comment: yes, some interaction is always necessary, but not necessarily directly with the entity hosting the wallet. There are some EC crypto tricks to do this (often mentioned under "deterministic wallets" before): The wallet-hosting entity has a private key x, with public key X. The address-generating entity knows X, and generates a fresh private key y for each transaction. For each, it calculates Z=y*X, and asks the client to pay to hash160(Z). Afterwards, it can send a bunch of y's to the wallet hosting service, which can reconstruct z=y*x for each. Alternatively, the y's can be generated according to a predefined scheme instead. -- Pieter ------------------------------------------------------------------------------ Learn Windows Azure Live!
