so i have a few questions / concerns. I love the product and the signing transactions without a hot wallet loading a key, but I want to be sure its a good method for cold storage security.

1) if the trezor breaks or is stolen it can be recovered by a 12word seed. How can i secure this code so that it cannot be stolen and used to take access from a different trezor?
2) what measures are in place to detect / prevent lo-jacked trezors or malicious code/components?
3) does the trezor retain access to all its addresses and change addresses? Can I constantly reload it to the same address without compromising the coins?
4) how does the trezor generate an address - could it be replicated based on the physical design?
5) can the trezor wallet be accessed using the seed but not another trezor? What if trezor goes out of business and you cannot buy a new trezor to load with the seed?
6) I heard a single trezor can hold multiple distinct wallets under the same seed but different passwords. How could I set that up to store spending quantities seperately (and secretly) from my long-term storage address?

I want to use this as a fuctional backup for the majority of my bitcoin funds, with the seed safely stored in a few offsite files/safes and some safeguards (password?) on those. I want it to act as the payment address for my mining and not worry that it may not be accessible if something happens to the trezor or trezor support.
