Multiple markets / models for single security

This may be a newbie question, but…

How does OG treat the situation where you have the same security which may have different prices either because of different markets or different pricing models? If OG doesn’t support this out of the box, when what sort of development for me to get OG to support this. This is very important for what I’m trying to do, and I’m willing to spend major development effort to get OG to support multiple prices for the same security.
