I'm not a programmer and C makes my head hurt, so I say the above based on the README and am likely not 100% correct.   I understand the need to continue on READY based on 'captive portal' situations (DNS redirect and the like), so would adding a quick IP check  like the following  be bad idea?

This is probably something you should take up with the ConnMan mailing list as they've decided that the network is available (online) when in either ready or online states - I can't say if adding an IP check will accomplish anything more in such a situation.

If the ConnMan connmand-wait-online solution isn't working for your circumstances then (assuming you get no joy with the ConnMan developers) rolling your own solution in /storage/.config/autostart.sh might be the next best thing.
