Seems I'm getting a Nanofury to replace a dead Bluefury. Anything I need to be aware of as regards getting the Nanofury working on BFGMiner on Linux (or indeed OpenWRT)?
You'll have to build hidapi for OpenWrt and recompile BFGMiner to use it.
Cheers Luke-Jr. I think I'll stick to the RPi then.

I hear there are significant problems with Nanofury on the RPi's buggy USB stack...
I plan to be looking into this in the upcoming weeks, but it may be a hardware issue I can't workaround.
