It generally looks like the same folk that designed homeplug products were involved in moca, with similar behaviors as described below with hardware flow control and the like, in addition to possible underbuffering and issues with shared media backoffs... http://caia.swin.edu.au/reports/130121A/CAIA-TR-130121A.pdf http://caia.swin.edu.au/reports/130417A/CAIA-TR-130417A.pdf But we lack hard public data on how the moca devices actually work or public testing.
