Agreed, however as it needs to last for a long period of time, it should 
not be too under powered.

Was the MT7986AV, MT7976DA combo considered? Has 4x4 for office 
applications (MU-MIMO), so might be useful for corporate or soho use.
It also has more horse power to run some local services

What's the price difference with 2GB? For home automation purposes and 
other virtualisation applications it might come in handy.

Great idea!

Nice to have the connector, would be great if a supported USB JTAG 
adapter could be supplied as an option.

Or just have 1 or 2 existing Banana Pi boards with OpenWRT branding? The 
schematics are not really making much difference for most people. Having 
all SW FOSS does.
