One of the practical challenges we ran into was powering the damned things in embedded environments--PoE can handle this neatly. Another part was working out if cooling became an issue in our chosen environment...we figure we'll cross that bridge after alpha testing shows how things go. I suspect a small fan and convective cooling will be sufficient, if not a big heatsink built into the case.
We also looked at using BeagleBone Blacks for the same application. The main draw of a Raspberry Pi was that you can replace them easily and they're good enough for an MVP until you can justify developing a real embedded system.
Running power drops, especially when we're already running Ethernet out to the little gizmos anyways, is annoying in our environment. More to go wrong and the like. :)

Sure, I'll bite.

Why did you have trouble powering them? No access to regular plugs in your environment?
And yeah, we'll have to see if we encounter any issues with cooling as well.
