Not that I'm aware of, and I suspect that the whole idea of mesh radio is necessarily so closely tied to the specific hardware that for this to be practical, there's have to be some canonical physical implementation available for developers to program to.
For what it's worth, what I settled on is EnGenius's FitXpress products. But I'm not necessarily recommending that, I'm a bit ambivalent to it. Within its normal operational envelope it works well, but its range is far lesser than the TP-Link device I replaced, and rebooting one of the WAPs in the mesh takes seemingly forever (like, 10 minutes!).
