Were you asking about power-LAN because it might introduce issues, or just as a convenient way to connect the Pi? Fortunately my Pi is about 30cm closer to a network switch than a power socket so a direct connection is actually easier I don't own any power-LAN adaptors right now but I've experimented in a few homes I've rented and old or new it's always been a poor experience.
Have also tried experimenting with latch times as high as 1000 but it doesn't seem to make a noticeable difference. There have also been a few under-voltage warnings popping up so I'll need to sort that out before fiddling around much more... Probably a job for another day though.
