this site here http://forums.smallnetbuilder.com/showthread.php?t=1142 shows that the unit can have SSH enabled by accessing a page called support.html.
this other site here http://forum.wegotserved.com/index.php?showtopic=6210&mode=threaded shows that the password for the ssh interface is in the format: soho + admin password
my guess is you could run a shutdown script using ssh.
as for wake on lan, i don't think it has it.
Thx, will try it out
