I had to recently roll my own signage solution and have built something I think is pretty compelling using Yocto[1]. I'm using CuBox-i devices running Linux and Midori (which is based on WebKit). I don't know if it does accelerated rendering but the boxes are much more powerful than Pis (and are a lot less dev-kit-y than Pis). If nothing else, hopefully a pointer to Yocto will be useful to you - it's pretty great. [1] https://github.com/luciddg/kiosk-yocto https://github.com/luciddg/kiosk-yocto
