The prototype version in the OP got more or less scrapped and rewritten with the release of REM4P, current version is working well. All decoders are in and working, multiple accounts, remote connecting/wakeup without having to port forward UDP 986 on client side and probably most importantly the input system from REM4P is in.
Besides bug fixing few features left - Auto configure PS4 port forwarding on local network, cloud storage for accessing accounts remotely.
