I bought an M1. I've been trying to migrate to linux. This is one of the few sticking points.
It seems like for every other model of slingbox the embedded player is a way to use the product in linux.
I wouldn't really care which approach you took to supporting linux for the M1 & M2, but I have a hard time seeing how it would take a few of your engineers more than a week or two to make it happen. PLEASE! - gnu + linux support for M1 & M2
