This is the response I got from Trezor:
It would be great if the team @Maidsafe could help to push this conversation forward with the folks at Trezor. @SarahPentland and @dugcampbell, is this something the marketing team could address?
Getting support on a hardware wallet like Trezor would give many people much more comfort in holding MAID. I think it would also incentivize support for Safecoin in the future as well as simplify the MAID to Safecoin conversion.
