I've looked at IHP briefly a number of times and the thing that always turns me off it is the fact that it's perhaps _too_ batteries included.<p>When I read the pricing page on IHP's site, and see something like "Email confirmation" (for authentication) having a price associated with it, it makes me assume that IHP is sufficiently locked down that I couldn't just build that feature myself. Either it's not, and I can do, and I've got the wrong impression, or it is, and I worry that IHP having that much control over my codebase will make other things that it doesn't support much harder than with other frameworks.<p>I'm all for the business model of well integrated, well supported plugins for the framework, but a closed, tightly controlled development environment that I can't break out of as I feel is necessary isn't something I'd bet a company on.
