At $dayjob for Collabora, we've been working with Valve on SteamOS,
which is based on Debian. Valve are keen to contribute back to the
community, and I'm discussing a couple of ways that they may be able to
do that [0].
Immediately though, they've offered a free subscription to any Debian
Developer which provides access to all past and future Valve produced
games [1]!
