I’m not sure if they are going to have a clause in their contract which says “No terrorist clients”, but UK startup Cellcrypt is looking to raise several million pounds for its voice call encryption technology which works on mobiles over VOIP. It’s already closing in on deals with multinational companies and the British government, so it sounds like it will be vetting who it works with, and it’s understandably waiting for security clearance from the UK and US authorities. However, with eBay potentially looking to sell off Skype at some point, I doubt they’ll be looking for quite the same assurances from any new owner.
