I have read the following:
https://github.com/bitcoin/bips/blob/master/bip-0016.mediawiki
https://darkwallet.is/bip16-17
However, I would like to know, can one specify a pay-to-script hash that includes another pay-to-script hash?
E.G.
Script for payer: DUP HASH160 EQUALVERIFY CHECKSIG
scriptA: DUP HASH160 EQUALVERIFY CHECKSIG
Can one include a CHECKSIG operation for another script inside a script referred to by a pay-to-script hash?
I'm probably not communicating this clearly, but I would basically like to know whether I can "daisy-chain" pay-to-script hashes together. Let me know if I should add more examples, or what changes I should make to this.
