www.openenergymonitor.org has an option for voltage and frequency measurement; as far as I understood it might also be capable to measure the phase shift between voltage and current (at least Trystan mentioned something in that direction some time ago), thus the power factor - as every measurement actually is done in software, there should at least be the potential capability. There are certain very expensive devices that do all you like (e.g. http://www.fluke.com/fluke/m3en/solutions/pq/), but I am not sure if your want to spend that much ;-)

Hi Gebhard,
that looks really helpful -- hadn't heard of openenergymonitor before. Thanks very much for the tip! I'll give it a go.

This looks also quite promising (indicating that there is more in the pipeline by certain vendors): http://www.microchip.com/Developmenttools/ProductDetails.aspx?PartNO=ARD...
