This idea will likely be appalling to many here, but it's an interesting and novel concept -- a promo DB folder with trial versions of, say, five products you can install if you wish, and the contents of the folder refreshes with new stuff every so often. If Dropbox is selective about the stuff it lets into the folder, I'd be up for it. It's kind of like all those subscribe-to-a-box-of-stuff services that are springing up.
