This looks pretty impressive.
Do you guys have a design or a price in mind?
Which materials are you planning to use to mint the physical coin?
Because the precious metals might not seem affordable to everyone. If you're planning to mint 10,000+ units in your first batch, I'd recommend using Brass.
I see that you are going to use a cryptoprocessor along with an NFC tag/chip.
Can you share some more information about the cryptoprocessor?
Do we need to use your application to generate a key, or can we generate one ourselves?
Watching.
Also, you might want to post it here: https://bitcointalk.org/index.php?board=217.0
I'm sure there'll be a lot of interest.

Using a cryptoprocessor to lock
secrets in a tamper secure way is also far safer than using an easily tampered hologram (e.g.
Casascius) or a scratch-off (e.g. Little Bit of Coin)

Inscription: Generate a bitcoin secret (private key or seed mapping to private key) unknown
to the minter but using entropy provided by the minter, with probabilistic evidence that no
cheating occurred. Optionally, the minter can view an audit report in which she can verify
the entropy she provided was probably used in the bitcoin secret. The minter can enforce an
arbitrarily high probability that her entropy was used, with more certainty requiring more
time during the inscription phase.
