I generally have two strategies for dealing with a Future(Just(x)):
Using maybeToFuture. @davidchambers just posted an implementation. I use this when Nothing represents an actual error in the code (one that can only be recovered from by my generic error recovery procedure, which usually reports the error and crashes the process).

Motivation

Use a Raspberry Pi as a bridge into my home LAN. The pi is plugged into a switch, which is plugged into an airport express, which is plugged into a cable modem; Nothing fancy.

This isn't a tutorial. Just some example output from a working setup.
