How did you get the Dropbox directory synced? Did you have to install it manually on the Whatbox? Because that's how I used to do it when my torrent box was at home and I was browsing at work, and that's natural and easier for me. I'm going to wait until I switch plans though because I don't know how much customization they would copy over, if any.
As far as getting it back home, someone a few pages back showed me a function on CuteFTP that synchronizes a folder on the remote box with a folder on your home computer, and I've been using it ever since. I have it check the directory every 30 minutes, and if the remote directory has changed in any way, it makes my local folder match it exactly (so if I delete a torrent, for example, it will delete it from my hard drive at home too, because I have already copied it to an appropriate directory or am just done with it).
If you can't figure it out from the post a few pages back, and want to use it, I can go into more detail later when I'm at home and can see the steps exactly instead of just guessing.
