Re:I think AudioHighway's is unenforceable. (Score 1)

I've briefly reviewed the claims and they're pretty broad. The only obvious circumvention strategy is to avoid the "greater than real-time" transfer of compressed audio to the target device- not an attractive option. I haven't yet had time to review the preferred implementation, but unless this is really bad (unlikely) I think they've got something here. However I suspect they'll make licensing proposals to Diamond et al that are quite reasonable, to avoid incenting them to file an invalidation action grounded on e.g. prior art.
