Please note the CAA cannot support in any way a product which is not a certified installed item - they have no authority over such.
Expecting the CAA to back say FLARM (a non certified product designed for mostly DIY installations, usually in the "portable" class) is a bit like expecting ATC to give you a clearance in Class G.
The only way to push a product like FLARM in the current UK regime would be appropriate publicity in all the various places, plus pilot shops selling it cheaply.
