             | An issue with BLE is that there is a lot of IP in the
             | typical software stack and bill of materials. Its one thing
             | for the protocol to be too simple (for example in cases
             | where IEC 62304 are to be applied) but its another thing
             | entirely to have no way to audit the stack that your chip
             | vendor, who also happens to be your software stack
             | supplier, is selling you in certain quantities.
             | 
             | Of course, there are outliers like Nordic, but there are
             | in-liers, like Qualcomm. This field is rife with issues -
             | and, especially, with peer-based audio streaming, in
             | general.
             | 
             | Because we are approaching a point in the BLE grey-goo-
             | iverse where the CPU's are perfectly powerful enough to
             | _not_ have to peer audio, and can just be used in a network
             | topology - yet _the vendor protocols are designed to
             | disallow that happening_.
             | 
             | The sooner we disenfranchise (literally) ourselves from BLE
             | and just make the devices client/server instead of
             | master/slave, the better.
