List of GLBSE Business

[bixcoin]

Does anybody know if there is a complete list of GLBSE Securities with a short explanation what they are doing? I would only be interested in real economy businesses, no mining or ponzi-like "lending".
I am actually thinking in building a security myself, handling with real estate, which is my main business. The problem I see is that there is so many high % fraud, semi-fraud or at least high-risk operators, that people might not even consider to invest in a 15-20%/year low risk operation.
Any hints or experiences?

Thanks!
