1password is an excellent tool and yet its biggest flaw is the master password. All it takes is a simple key logger to gain access to my password kingdom. Is AgileBits planning to implement an optional, additional form of authentication such as SMS or a phone call? I'd even pay extra to ditch my own master password and use an RSA soft token or the like. Sure, seed files can be pilfered although this still seems a lot more secure to me.
