Thank you for your comment. Is there anything I can do about it or am I doomed to be ignored? Maybe I should summarize what this is all about. Here's why I'm trying to propose a new smart property protocol:

Colored coins match the digital property ownership with individual inputs/outputs of bitcoin transactions so one can't spend these coins without losing the digital property ownership. Cointrace matches the ownership with a bitcoin address and it even allows the balance of the address to be zero and still retain the property ownership. Colored coins require dedicated client application to carefully handle the ins/outs while Cointrace can be used with existing clients.

Mastercoin is a protocol too complex for a simple digital property control and also requires a dedicated client application. Its exodus address is picked and controlled by its creators (and so is the Mastercoin itself), introducing a possible point of failure. Cointrace is much simpler and allows anyone to create and control their own "exodus address" (called the project address).
