Will Aston ever become freeware/opensource?
No. We believe, that the only way to keep Aston the way it is now is to keep it being developed by a certain group of professional programmers. If you want a free opensource shell, try using Litestep. If you just want to add more features to Aston, try using our open plug-in SDK, which has sources of some plug-ins. In certain cases we may consider making sourcecode of other plug-ins available to the third party developers.
