PPSi was tested on WR switches and SPECs
against a number of commercial/prototype devices from
different vendors. The results are very promising and a detailed
report can be found here: https://www.ohwr.org/project/ppsi/wikis/Documents/Report-from-the-PPSi-inter-operability-test
Thanks a kit to Maciej Lipinski for being at the plug fest and writing the
detailed report.
