Small comment: the current implementation in the reference client uses a custom
script encoder for the UTXO database, which stores every (valid) send-to-pubkey
as 33 bytes and every send-to-pubkeyhash or send-to-scripthash as 21 bytes.
So for "standard" address payment, there is no storage impact of using P2SH
instead.
