There are already a few places in the source code where that is done. @p{brk}

I think Satoshi's done a darn good job of anticipating future needs.  The wire protocol and database serialization formats both have version numbers, as do bitcoin addresses.  The core transaction mechanism is @p{(it}very@p{it)} flexible (I worry that it might be too flexible, but that's why we've got the TEST network to see if we can break it). @p{par}

I can't think of anything simple that would make it more future-proof.  If you're worried about SHA256 getting broken or the 21quadrillion Bittiestcoins not being enough... then you worry too much.  Stop worrying, you'll just suffer from analysis paralysis and get nothing done. @p{brk}
