With the advent of Steam OS, which should see an uptake in the number of Linux deployments in the home, wouldn't it be nice if GOG released an Official Emulator for it's games catalog.

You could maybe run of the Wine emulation system, but with a tweaked, more user-friendly and * shiny* GUI front end and a more robust and comprehensive library for running GOG games.

That way people who use Steam OS will still be exposed to the GOG games library, a win-win for all.

PlayOnLinux|PlayOnMac and CrossOver already have installation "recipes" for most of the popular games on GoG

True, but most people who are not familiar with those software, and would rather have something that is supported by GoG itself in my estimation would be more inclined to make use of it.

Think of it this way: If someone wants to play GoG games on SteamOs is but is not familiar with Linux (other than quitting the Steam client interface, and returning to desktop) can come to Gog.com , install the official emulator and start installing games to the SteamBox.

I think the best solution would be more skilled programmers working for GOG. I was surprised at the number of people they said worked there (63) during the "Letter to Santa". Between the people they have doing tech support for Windows and Mac, troubleshooting games for Windows and Mac, sales, negotiators, and website tech, I find it hard to see GOG expanding even more.
