One of the things that I recall liking from the ideas I read (didn't read all of it) was the idea of the support time not starting until the first ticket is submitted, with a maximum deadline for support. I've never needed to get any real support on any of my licenses, but the idea of the support window being flexible sounds nice.
The other was that when someone owns a license (version), they get updates for that entire line for that version. Sort of like the perpetual license once offered by IPS, except that theirs is limited to the version the customer paid for.
With this being the area for feedback, I'd toss in the idea that perhaps when someone buys a new license (not including renewals), that they still get 6 months of support, but that the support starts on the first ticket, with the maximum being a year, with having access to downloads of that version for a year. If they use up their support (say they submit a ticket to have it installed after the first day), then they renew support 6 months later, their download time wouldn't extend any. Since I barely ever need support myself and already have the IPB licenses that I'll need, this wouldn't affect me, but I'm sure it would attract many more customers, especially now.
Just thought I'd toss that out there. Whether or not it makes any difference, again, doesn't affect me since I already have my licenses. Just want more people to buy IPB, so that the product has financial support and can continue to grow.
