We're planning to support payment protocol in Trezor as well, if it counts. I think it's a missing piece in absolute security of hardware wallets.

Yup, that's always been the plan :-) 

Any idea how much work it is, and would it be a v1 feature of the Trezor or added later via firmware update?

Our plan is to add support for that into v1 firmware, but it also depends on readiness of surrounding infrastructure; mainly if there'll be support for payment protocol in multibit in the time of v1 release (I suppose that the Multibit will be the first wallet  compatible with Trezor AND supporting payment protocol).
