Hi everybody, just thought I’d throw my opinion in here. The URI scheme is a nice idea, but this ignores the fact that hardware wallet vendors do most of the work on talking between the computer/mobile and the wallet on a lower level of communication. In the case of BitLox, the base protocol is Google’s ProtoBuf. The commands and transaction data is in a “schema” which is then encoded in different methods accessible via ProtoBuf (depending on the data being sent). The advantages of this protocol is that it can be implemented on a wide variety of platforms. (but that’s a whole 'nother discussion) The URI would be handled waaaaay up in the specific application (such as the mytrezor wallet software or the various standalone wallets) - nowhere near the actual hardware communications layer.
