am i blind or is there not even a featurelist (and requirements list) for ISP config v3 to be found anywhere?
There is no feature list for ispconfig 3, we will make one when we rebuild the ispconfig.org website in the next few months.
We have used both ISPconfig 2 and 3, in lieu of a feature list I can tell you that both are excellent hosting software. ISPconfig 3 seems to be more centered on newer technology and I think it's obviously where ISPconfig is headed in the future. We've used it since 2008 on all our servers to provide hosting to customers, and I can safely say that it more than meets any requirements. The only thing that seems to be lacking at the moment is bandwidth tracking/storage tracking/bandwidth quotas per site and mailbox, though I may have missed some more recent developments here.
