I know this is supposed to be a resource manager, but what if you wanted to adapt this script into a sort of auction system? You could add an option to set it up as an auction, add an option for the BIN, add an option for how long to have the auction run, and then develop a few pages for current and expired auctions. Then auctions that were successful(sold) or unsuccessful(unsold)
I think this would be interesting. It has just about everything already there you'd expect and I assume they'll be adding a shopping cart system in this at some point. So yes, this sounds like something that could be added without much effort.
