OK, so I want to send a beta version of my game to a bunch of people, and I'm moving beyond the 'friends and family' stage to a moderately large group, so I'd like to protect this beta in some way. I own a pro copy of SoftwarePassport and have accounts setup with Plimus and BMT. I also want to make it relatively painless for the beta testers. Obviously, I don't want to make them pay anything or submit credit card info. Should I set it up as a product in Plimus, and then send each tester a one-off coupon for a free copy (is this possible?). If I do that, will they still need to submit credit card info? I guess I could just generate a standard version with a single key, but set up to time out on a specific date - maybe 2 weeks hence or so. What do you guys do?
