Now I had the same question, David; and of course it raises the matter of proclaiming one's (lack of) taste in suds.
Another option, which I'm borrowing from a conversation with Dan some time back, on stopping Click-stands from digging into soft sand/mud/whatever, is to cut a hole in a tennis ball. I guess that for the Helinox one could also cut 2 tennis balls in half, so they'd pack nicely, but that bodge wouldn't have the same je ne sais quoi as empty beer cans.
