Sythe should use a system similar to MMOE used.
The two people would have to initiate a trade on the actual site, and then both parties would confirm it was them, and this was the only way you could leave feedback(vouches). You had to go through the whole process.
That's a little excessive. I almost did something like that with my coding for the system I made, however, if they wanted to, two people could complete the form at once and give eachother links.
I might add an optional field for a trade description as well. I think it's a good way to log trades, even vouches.
