I have brought this up some time ago about having an online shared storage folder for music and other things of that nature (for the X'ers). I have created such folder using Dropbox. Right now I can store up to 3.5 GB but not all of that is freed up since I use it for my work purposes also. However, I don't imagine if its cleaned up once a week or even once a month there should be any issues with that. PM me if interested and I'll send you the link.
Dropbox is a free download by the way. You can link as many computers to it as you want and as something is uploaded or downloaded, each linked cpu is updated automatically.
