I am always fascinated by the innovations that Bobby comes up with. Most of you know similar products have been done before, but I think there are probably even more ideas waiting to be "tapped." I'm not sure there is enough room on the TC plate, but if you were to put a few of these on there: http://www.chicompany.net/index.php?main_page=product_info&cPath=376_1_3_260&products_id=3276, I could see people interested in an easy way to convert to ball lock without using a tall sanke coupler + expensive fittings and such. Obviously you would need to find room for a prv as well. You could maybe even use that setup as the racking cane and blow off by hooking up ball lock disconnects to it, then hooking up co2 to transfer. The idea isn't necessarily fleshed out to its entirety with benefits/pitfalls, but thought I might throw it out there. There are a lot of creative people here and someone might be able to build upon it.
