I don't expect you to give away any copy protection secrets but I'm wondering if you can give some details about installs etc..
As an example I purchased DVD Rebuilder which contacts its online database when you install and enter the registration for full functionality. In that scheme you are only flagged if you have more than 5 concurrent installs registered and after a period of time the oldest is discarded. IOW, you don't have to worry if you play around with lots of software and back-up and restore system images that your registration is going to be hosed since you can just reinstall should the need arise.
I'm just a bit cautious with some of these registration schemes because some are really intrusive. I won't buy a product that won't launch if your internet access is on the blink(as example some authoring programs decide at random when they are going online to check your registration. If your ISP is down, then you can't use the software that has nothing to do with being online per se as a newsreader would have.)
I just want to get an idea how much hindrance I'll have to endure if I purchase(all copy protection is a hindrance so it's a matter of degree. I looked into it a bit when I created my online site before I finally gave up and went the donationware route. My utilities are small convenience apps so the registration model didn't work for me. More hassle than it was worth.)
