I approve of this idea. Counterparty has the same problem. Their API
returns a unsigned transaction that is formed differently from how
other unsigned transactions, which causes friction. Someone needs to
write up a specification that is standardized so that all unsigned
transactions are of the same form. Basically the signature section of
the should contains all the information required to make the
signature, and it needs to be encoded in a way that the signing
application (a blockchain library like BitcoinJ or BitcoinJS) can tell
that it is unsigned.
