Valve has informed developers that they are working on a method for adding
online multiplayer support to games with local multiplayer functionality. This
was done privately, but
Ars Technica notes
that Valve's letter on the topic
is posted on the Unity Forums
. Word is this will require the addition of no
online features or servers, and should launch in beta form on October 21st.
Interestingly, since this emulates local multiplayer, only the host needs to own
the game being played. Here's the FAQ on the topic:
When is the Remote Play Together Beta launching?

will be able to access this feature.
What games will be included in the beta?
All games tagged with local co-op, local multiplayer, or split-screen will be
Do all players need to own the game in order to play it using Remote Play
Remote Play Together is designed to re-create the experience of playing a game
with a friend at your PC. Only the host needs to own the game to start a Remote
Play Together session with their friends.
Does this mean anyone can play my game without buying it?
Similar to visiting a friend’s home to play a game, Remote Play Together is
designed for small groups of Steam friends to enjoy games together. In order to
play a game using Remote Play Together, a host must own the game and manually
send an invite to each friend to play. When a game is exited, the remote play
session is terminated. We don’t believe it’s feasible to use Remote Play
Together to avoid purchasing games on Steam entirely, and like other promotional
tools and features, we believe the additional exposure and fun players have will
lead to additional revenue and player growth.
Can I opt-out of the beta?
Yes, though we would encourage you to try things out in the beta. If you prefer
not to participate, let us know by emailing the Steam team at
