I would guess that the more reliable way of setting this up would be through a separate entity managed, and officially owned, by someone else. Would be interesting to see if this is a service that could be offered by solicitors, essentially as an extension to your will? Or, perhaps find someone you trust to own and manage payments for the site.

A good way of enforcing this would be to only allow software to be distributed on 3.5" floppies and see how many people bother installing adobe creative suite!

Before you know it they'll be banning the playing of your own music in case someone else hears and records it.

I'd have to say Internet Explorer is somewhat lacking in some areas such as SVG Support:
Opera: 94.16% A+ Pass
Firefox: 60.40% C Pass
Safari: 64.23% C Pass
IE: 0.00% FAIL
