Please advice (which chip to count up/down and DAC) Onsemi has some digital potentiometers, which seems to meet OP's requirements. The CAT5133 has a V_hi of 16V, and it comes in MSOP, which is...

Does this 'component' exist?
APC makes ethernet controlled power distribution units. But those are controlled over ethernet. Usually, you telnet into the offending device's PDU, and cycle power. Sparkfun has...

html GUI for variable inputs to AT90USB controller
It is quite possible that you want to start from the RNDIS example in LUFA. This will emulate a RNDIS network adapter, that any supported host can point their browser to.
