Of the listed applications offered by MacUpdate (the first list), the three with asterisks ( Little Snitch Intaglio TechTool Pro) will not be offered unless x number of people purchase the package thereby "unlocking" it and making it available.
I had a sneaky suspicion that's what it meant, but I thought I'd check before passing up the offer.
Shame really, because I was after Intaglio more than anything. I'd rather just pay for the damn application than take my chances with something like this. Anyone know what the track record of offers like this are?
