can you guys create some sort of trezor multisig feature where you create a multisig address using 3 trezors and then send the trezors to 3 locations. that way there wont be any single point of failure (extra secure).
TREZOR supports multisig for quite some time (since December 2014 to be exact).
Unfortunately there are not a lot of usable options how to use it.
What we are working right now is to integrate TREZOR into multisig wallets such as Copay and this should be ready soon(tm).
