So, as far as I know, there are no wallets/services that allow for Trezor+multsig (well, there's Greenaddress, but that uses their servers to do stuff).
Any chance Coinbin could be the first to do this?
It will be even very useful if it's possible to do the same with Coinbin as do this version of electrum:
