Er, no— if a node controls the private keys for a transaction, and that transaction makes it into the chain then it can safely assume that its unspent (at least once its buried a few blocks into the chain). This is the essence of a SPV node. What it can't do is perform this function for txn which aren't its own. Though the system could be extended in a compatible manner to make this possible: https://bitcointalk.org/index.php?topic=21995.0 ------------------------------------------------------------------------------ Ridiculously easy VDI.
