RealWorld for more domains than webapps

[seagreen]

RealWorld is a specification for a blogging app API, meant to allow comparing multiple frontends and backends for it written in different languages.

I think this is a really great idea, and should be copied for other kinds of apps.

Some possibilities:

• Small game
• Lambda calculus parser+typechecker+interpreter
• Chat server
• MMORPG (one with very few rules, perhaps just "move left/right/up/down")

For reference, the RealWorld PureScript frontend is 3000 SLOC, and the Yesod Haskell backend is 1700 SLOC.

Another question: what should these apps be called? For example we can't call the chat server "RealWorld Chat Server", because RealWorld is the name of the specific project, not the genre. Perhpas "Acme Chat Server Specification"? I have no idea.
