Many customers in other countries want our US version. They are pushing on their governments and the US government to get it. This is already happening.
Couldn't you set up a company in the Netherlands or some such place that allowed you to export to the rest of the world? There could be a US version of Netscape, produced here in the States, and a strong international version produced by a different company, using non crypto technology licensed from Netscape and a crypto engine produced entirely offshore. You could make the offshore firm virtually worthless by forcing them to give all the money to Netscape proper in the form of licensing fees. It wouldn't matter who owned it, so you could give the franchise to a Dutch national without giving away the store. I seem to remember US companies getting around restrictions on doing business with South Africa using a similar strategy.
