That would be a huge step forward, and would make me seriously reconsider Signal. I know this would create the identification problem in contexts where one actually wants to give proof of his/hers identity by pairing the client to a personal piece of hardware, but I believe/hope there are better ways to accomplish this without tying the account to a phone number (==cellphone). Also, old netbooks can be purchased literally for the cost of a pizza at flea markets, and they're much much better platforms for building secure communications terminals; a lot more reliable and trustworthy than cellphones and tablets with their closed operating systems.
