Arnaldo,
Certain Sun systems do have this sort of feature-- it has been called
Lights Out Management (LOM), Remote System Control (RSC) and the like.
Basically, proprietary, pre-IPMI management controllers of varying
functionality. As DaveM mentions, this isn't it, though... :)
There is ongoing work to support such controllers (e.g. on Sun E250
and E450 servers).
