This is something that I am asking to hopefully save some time in unnecessary research and development. I think BitCoin does offer a mechanism to make it so that more than one signature is required to transfer BTC from an account? Please advise if you're aware of such a solution, or the merits/uses of such.

According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

This has multiple use cases (some are explained at http://bitcoin.stackexchange.com/questions/3718/what-are-multi-signature-transactions), but software support is still in its infancy (http://bitcoin.stackexchange.com/questions/3557/how-does-one-make-multisignature-transactions-with-the-bitcoin-client).
