PwrCtl works with bluetooth
After a short discussion on linuxfr, I bought a bluetooth usb adapter to test PwrCtl over bluetooth. It works very well over TCP/IP. You only have to create a PAN between your PDA and your PC to obtain an IP address.
For linux, read the gentoo documentation. For windows, read this microsoft how-to. I am going to update the pwrctl wiki in few days.
