Is this going to be a "sync this folder" app, or a "access your files when you want them" app? I use dropbox (and think it is awesome) but I don't necessarily want to have full-time, online syncing of 2GB with my phone. But I would like a nice interface (other than the website) to be able to pull down the latest version of files that I keep on dropbox and use on my phone.

In any case, kudos to you for taking this on. Looking forward to seeing what you spit out.
