Transfering files

Just wondering if anyone knows of a good program to transfer files from pcs to the phone without going through a direct connection.  For example, I do alot of 'searching' on my work pc.  When I find something I want to install/put on my phone, I have to connect it via usb cable and transfer the file (or pull the sd card out and transfer it that way).  One option that I sometimes use is Live Mesh.  It does a decent job but it's still in beta and there are size limitations along with not being able to transfer folders.  Anyone know of something similar to this?

I was hoping for more of a standalone app for the device (a web interface for the pc side is fine)... plus, this has a 2mb upload limit which is way too small for most of the stuff I need to transfer.  This seems alot like microsoft's skydrive (which i never could get to work consistently).
