Cool. Let me get some advice on what the best way to protect the idea while sharing it with someone and I'll get back to you.
I don't know that it's even that great of an idea or anything, so I don't want to over sell it. It's something that I wished I could purchase but as far as I know no one makes. There could be reasons for this... it could be more expensive to produce than I think... it could be that there are design limitations. That's the reason I don't want to drop $400 or $500 on patent searches at the moment. For all I know someone has a patent on it, or tried and decided it wasn't viable.
