The first thing we need to know is what you want to use AfterGRASP for.
Our primary concern being competition with our own in-house business, we have to restrict what commercial licenses are used for.
We don't expect you to email us your business plan, or disclose confidential business details. However, we don't want to be caught in the awkward position of providing key technological advantages to potential competitors.
As for pricing, it's on a case-by-case basis with very low rates for enterprises that we would never be part of, like children's educational software, or dedicated kiosks. As the business gets closer to our own, the price rises. Same with support; if you can live with open support provided primarily by other users, great. If you require special features or guarantees of support for some time period, the price can rise dramatically.
But first, look at the beta copies, be sure this is what you want, and only then contact us if you can live with these restrictions.
