I use a free web-based service called logmein.com for remote access to my household pc. It's very useful. I do a lot of music downloading on L*mewire, so I remote access my home pc through PIE using their service and email the songs to my phone. It starts off with the full service that includes direct streaming and downloading of the files from you pc to your ppc. If you dont wanna pay, you have to go my route with the emailing of files to yourself. It's worth the money in my opinion, but I'm cheap as hell. Hope this helps.
