Why? If somebody is sending me bitcoins, then they'll have to get
either an address or one or more public keys from me. OP_EVAL just
lets me give them a short address that represents an arbitrary number
of keys combined in an arbitrary way.
I agree with Gregory: it shouldn't matter if that address is
HASH(public key) or HASH(op_eval_script), the issues are the same (if
you lose or cannot re-create the key/script then you're in trouble).
Maybe I'm missing something; are you worried that blockexplorer won't
know that coins sent to HASH(op_eval_script) are actually a
complicated transaction until the coins are spent again? I'd consider
that a feature, not a bug, because only the people involved in the
transaction need to know the details until after the transaction is
Feel free to contact me about your 'tiered implementation for thin
clients' -- I don't think OP_EVAL will make that significantly harder.
I also agree with Alan: using OP_EVAL is not mandatory, I'm proposing
that CHECKMULTISIG becomes a standard transaction type.
