Did you read BIP 16? @p{par}

So there is no manipulation allowed AT ALL. @p{par}

A maximum of 1,000 "naked" OP_CHECKMULTISIG operations are allowed in the scriptSigs and scriptPubKeys of transactions in any given block. @p{par}

We had a block earlier this month with 1,8000 scriptSigs, so I think we are uncomfortably close to that limit. @p{par}

BIP 16 "hides" the CHECKMULTISIGS in the serialized script, so more of them are allowed. @p{par}

At the very least BIP 17 is harder to test@p{--} Luke had to test on the main network because I was naughty and wrote and ran a BIP-17-transaction-stealing bot (sorry, I couldn't resist). @p{par}

I have zero commercial interest; I am not being paid by anybody for anything right now. @p{brk}
