Multi-signature user interface

[teste]

Let me see if I understood the (linked wallets).

1- I create 3 wallets
2- Will be 2 of 3 to spend.

So I create a wallet on blockchain.info service. A wallet on mobile app and an offline wallet on Armory.
Will be possible to on all addresses that I generate on any of the 3 wallets, only be able to be spent with 2 of 3?

If yes, I think is the perfect security solution.
