You could use Wake-on-LAN to turn a system on, but I don't think you can
reset or power off the system. What ever you use should give you some
authentication/authorization and hopefully encryption so that you don't
have just anyone rebooting systems. IPMI 1.5+ will do this, but
Wake-on-LAN does not.
