Sure, but permissionless+custodial often ends badly, ecash is not a new thing, I just can't see how it fits into Bitcoin right now, but there may be ways and hence my interest. BTW it was a honest question, no trolling intended.
I have been using it since TrueCrypt was abandoned and it's awesome, I guess your problem is that they have a dual license? But since one is the GPL I don't see a problem there?
