I would like to see this idea implemented. I am willing to donate BTC to the project if anybody wants to take the bull by the horns and go for it. I would also rather see it done under the auspices of the Bitcoin Foundation, but that isn't absolutely necessary.
And just so we are clear:
A no fee service.
Hopefully implemented into some bitcoin client.
Is rock solid before rolled out to the bitcoin network.
Is tested on some test network first.
Quantum
Count me in for donations to any serious efforts meeting this spec.
