You can do a dropbox type transfer on your WM. This is my favorite way of doing it.

You just network map a drive/folder on your pc and access that mappped drive using wifi on the ppc. Resco explorer supports network map drive access. You can install cabs over the network... there is no need to then move them over to the ppc. This will obviously only work when you are in range of your local network.

Your other solution is to create an FTP on your PC. Resco explorer also has built in FTP support. This way you can drop anything in the folder that you share on your FTP and access it from anywhere you have internet access from the PPC.

Both methods work very well.
