While it's cool to see people replacing Dropbox with OS alternatives, this only seems to capture a fragment of Dropbox's functionality. How, for instance, does it deal with conflicts where files have been changed on two machines independently prior to sync? Dropbox is (somewhat) clever about it, and renames the conflicted versions - and IIRC you can resolve the conflicts manually. At least both files are available on both machines - not sure how this situation is dealt with by lipsync. Dropbox push-updates are immediate. Lipsync relies on a cron job to kick off a receiving file sync. Dropbox will sync directly between clients on a LAN - great for when teams are sometimes working in an office, and sometimes at home. Dropbox maintains revision history - does this? Dropbox has a web interface, mobile apps, etc... I realize that Rome wasn't built in a day, but until at least the first two points are addressed, this isn't much of a replacement.
