First of all, I'd be really happy to see more people escrowing Mastercoin trades. But I'm not sure if the guys at bitmit are able to do proper escrow do they even know about Mastercoin and how to determine a successful transaction?
I'll be pleased to help. I appears that Maxmint is operating in the US/Europe time zone. I'm in NZ, so I will be online when Maxmint is taking a break. That'll make this a 24x7 exchange!

Trust:
I was one of the earlier buyers who bought 700MSC in 2 trades with Maxmint as escrow. I think we don't need to trouble JR with this. I'll be comfortable to send 5BTC to Maxmint as escrow, sort of acting as his sub contractor lol. After all, he started this valuable service. If Maxmint agrees I'll be happy to proceed.
Order book:
For starters, I've make a slightly more readable version of it here
https://docs.google.com/spreadsheet/ccc?key=0AoE8nAOEMIa7dElfTGo4UUlaRzhpTlVBa1NGbzExQmc&usp=sharing#gid=0If Maxmint or the rest likes it, it can be ported over to the original file.
Not sure how long before the distributed exchange is up. For the time being, I can make a Google Form for traders to submit and withdraw bids. That may be easier to track and does not crowd out this forum. Again, only if folks like it.
The new orderbook is great! I'd love to port this new look to the original.
Also, the submit form for traders would be awesome! Do you have something up already?
If you want to start escrowing trades I can hold your 5 BTC on an escrow address so people know there's at least a bit of a safety net. I think this is a great idea to get started. After a while people can rate you based on their experience and I can return the coins to you.
And yes, I'm based in Europe. Actually, the antipode of my place is a couple hundred kilometers east of NZ so that would be a perfect fit
