Hi everyone, I also have questions about trezor:

a) what happens if the domain wallet.mytrezor.com is down? I couldn't access to the device to use my private keys to make online transactions. Is there any option to download source code and create a webserver using localhost and a specific /etc/hosts entry?

b) how is the passphrase generated within the device when multiple wallets are used? Is the seed related in this process? Because if I use the seed to recover my wallets, the passphrase couldn't be generated unless you put it explicitly, so it'll be impossible to access to my wallets, therefore all my BTC will be lost.

Thanks for answering!
