I'm in the process of talking Jarred into creating a DSMC Quickplate Module (see this thread).
This baby would allow you to mount your beloved RED Bricks to the back of any DSMC module combination, without having to tether it to the brain, without having to use the expensive backpack system, without adding any weight you don't need. You'd simply add that module to the PRO I/O or the upcoming +1 Module (the one with the additional EVF/LCD port) and you have a very streamlined, short and light setup.
Jarred estimates its price to be around $1,000.
Please add your votes here if you want this product to see the light of day. Thanks!
EDIT: Prototyping phase has begun according to Jarred.
