I've read that btle 4.2, while it won't permit one to maintain multiple
links at the same time, will permit a device to quickly cycle between
multiple attachments.  A device could therefore move from one btle star to
another one several times per second, and route packets that way.
This puts btle in the same space as time slotted -- 6tisch (802.15.4e).

My gut is that btle will be *the* low-power mesh tech in ten years.
(Unless it's DECT...)

The other situation in which we might need more than ptp is when we have
multiple btle radios, or when we are doing any kind of layer-3 mesh with
multiple technologies...
