I've commented on the math that Mesh Dynamics uses to justify their system on several occasions -- needless to say, it's wrong and overstates degradation. More importantly, their systems is _extremely_ expensive. Meanwhile, groups like CUWiN, FreiFunk and others are developing free open source mesh networking systems. CUWiN's software (and, for full disclosure, I cofounded and coordinate the project) can be downloaded by anyone, it's under an open source license, and everything (including the developers' environment) is freely available.
We haven't implemented multi-radio solutions yet -- mainly because the bandwidth degredation hasn't been bad enough to justify it. But to do so, we're only talking about a few weeks of work -- which can be done by anyone who wants to add the feature -- and then you'd have a system that does the same thing as Mesh Dynamics, but is freely avaialable to anyone who wants it.
