This questions doesn't make sense to me. How can I answer this when I don't know what's in the vault? Even U2 themselves don't have a decent quality mastertape recording of Gloria (they are all worn out) - that's why they didn't get to add the song for the Best Of 1980-1990. So only God knows what are in those vaults, if there are any. Also, you haven't defined what you mean by "few days". Perhaps that might be enough to copy everything in their vault if their vault is pretty empty.
But just to try to give some sort of answer to this unanswerable question, I'd probably try to find footage of what Adam was doing (or overdoing) the night before his woeful missed gig in Australia, Zoo TV. Then once I've copied it, I'll sell it to the British tabloids. That should make me a good sum of cash.
Cheers,
