I've seen that 3M stuff. It's like Velcro, but there's no fuzzy side, both are hard and interlock. The key, though, is how the actual adhesive is. I don't think the Velcro bit is the weak link, so much as whether the adhesive works well, too well, or not well enough.

I've had pretty good luck with standard 3M permanent double sided tape, which can be removed if you're patient, but I'd never try to stick it to paint / drywall. Or should I say, I've stuck it to painted wood before, and the weak link proved to be the paint's bond with the wood, rather than the adhesive's bond to the paint!
