What about btcinve.com?
While I haven't heard anything concrete, I don't think Lab_Rat is considering a third-party exchange. BitFunder burned a lot of people pretty badly, and any exchange that gets big enough is going to run the risk of attracting legal attention from the US and having to shut down. I have gotten the impression (which may be incorrect) that Lab_Rat is investigating an "in house" solution that will allow the automated trading of LRM bonds (and only LRM bonds).

For myself, risk isnt a factor since Ive been with LRM from the beginning, and know the process that lead to the forum trading. I have no question in security, and trust 100% that If I want to buy or sell on here that everything will go smoothly. The issue as I see it lies in perceived credibility.
When new BTC investors are looking for places to put their money, having an automated trading process looks much more credible than forum trading. Having an in-house solution would most definitely remedy this. The other issue as I see it is that there are 2 separate forums for LRM. While this is necessary to isolate the trade threads, it makes it difficult for new buyers to see things like historical dividend payments, number of bonds sold, future company plans, etc.
Just my 2 cents.
