Hybrid SPV sounds like a good idea to me. Allows it to work out-of-the-box, then slowly gets up-to-speed with the full network - working low priority, or even not at all, if it detects a slow system or network link. Another idea is always distributing the client with a checkpoint that is only days old, then starting by pulling in more recent blocks, so it can transact. Following that, it will pull in progressively older blocks as time permits. --e89a8f3ba5c195a94104d0185030 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable
