Just bring RLP back and everyone will be happy (except godefroi and me, of course). I, for example, remade CAN, Serial and AES on G400 myself, from scratch, using RLP. I was swearing like a peasant, and even though I really hate GHI for having to reimplement — often in a great hurry — stuff that I was supposed to be buying of the shelf, I still respect them... due to the same fact that they actually [em]left a way to fix it[/em]. So, all in all, NETMF is still a win, despite my experience that G400 requires lots of patching for industrial/medical usage.
So, from my perspective, shall anyone care, it's very simple: no RLP, no business. Other than that, TinyCLR looks very promising, simply because [em]that's finally a move forward[/em].
