(I did get a reprieve on having to close the lab, but I have to update the whole campus as part of it). Anyway after some struggle with a bridge, I ended up being able to deploy openwrt to about half the campus so far. The two major blockers are the ipv6 issue I mentioned here, and the speed issues we've also discussed (though I can just throw hardware at it on 3 of the gateways). But I took a deep dive on some long standing issues in babel and finally got around to doing something about it, establishing a bug tracker, trying to make it faster, and do atomic routing updates and so on. In particular, it really looked to me as though a faster qsort would speed up babel by quite a bit but my first attempt at an inline version didn't work.
