Oooooh, I tried it. First nginx didn't find the socket. Guess 
why? Because nginx runs in a virtualized filesystem. Relocated 
the socket, now nginx says access denied, sure nginx and your 
server can run under different accounts, permissions should be 
tweaked accordingly, tweaked them, still access denied, relocated 
the socket a bit more, still access denied. Guess why? I turned 
out to be some kind of audit, selinux or something like that, it 
just fails with generic access denied error. Ok, FHS recommends 
/var/run, but it's rwxr-xr-x root root. Wut? Run a network server 
as root? Tried tcp, it just works.
