galitska, your question is not very complete. Perhaps you could describe it in greater detail, provide links to reference materials, &c.
The article How do I post a question effectively? has some excellent advice on posting complete questions that are likely to get good answers. Your question seems interesting on the surface, and I look forward to your reformulation of it!
