So AirControl "doesn't play well with other network monitoring software" (which one, and why?), and MikroTik "isn't built for what [you] need" (what's that?) - other than that, you don't give us any idea what you really expect. What are your requirements? Suggestions out of the blue: OpenWRT with quagga/zebra, hostapd, radius, olsrd, b.a.t.m.a.n. etc. etc, or you might want to have a look at Vyatta (no affiliation).
