In trying to hook up my Mesa Mark V recently, I had to resort back to my RJM amp Gizmo. This got me thinking that Pod HD500/DT amps accomplish signal and topology switching over L6 Link. Why couldn't Line 6 develop a remote breakout box for amp switching and loops. Sort of a cross between the RJM amp/rack gizmos and HD500/DT functionality, via a single L6 Link cable.

It requires a lot of cables to accomplish 4cm, amp switching, midi, etc. between a floor Helix and an amp. It seems this could all be accomplished over L6 Link, a single digital XLR cable, and a Line 6 remote breakout box (Amp Link?).
It seems there is similar functionality with Pod HD500x and the DT amps. Why not open up that functionality to any amp, rack, mixer, computer, etc.
The unit could be 1-2U, half to full rack width, with optional rack kit, with send/return loops, switching jacks and/or DIN jack with custom amp cable or generic 1/4" cables (similar to the RJM amp/rack gizmo concept, and maybe midi (could still require a midi cable in addition to L6 Link), possibly USB for remote computer software/midi control, maybe another L6 Link out for connection.
Personally, I would like to connect to and control a Mesa Mark V or a Mesa Triaxis & 2:90 stereo rig, and maybe have the option of switching to or blending with FRFR speaker(s). Running a single XLR cable back would be a dream!
A $299 price tag would be sweet, but RJM gets a bit more for their similar gear
