Small Networked Info Push Hardware

What would be the best way to receive information from a serial port (or USB serial connecter) and then post the data to the web (GET/POST).
I'm trying to make a power meter that reads the pulses from the LED on the front panel.
I have a Picaxe-08M with LDR and a Serial connector made and working, it outputs the number "1" on to the serial port every time the LED on the panel pulses. My problem is: I don't want to have a normal server running only to do that, and wasting power (defeating the purpose)...
Any ideas?

Thanks :D
