I would pay if I could get an openwrt router that was already set up with features like

- ad-blocking

- kid network vs grown-up network vs guest network

- blocking sites (on kid network), with easy way to temporarily disable or disable on a schedule

- safe and regular updates from openwrt, that I can trust will work even if your company goes bust (ie. your layer on top needs to play well with upstream)

(but I'm in Europe so might not be your customer)
