I've been having some trouble keeping all my media libraries in sync across my machines with Windows Live Mesh. It's getting stuck on certain files, but it won't say which ones, because that's just not how Live Mesh rolls. In searching for a solution online, I learned that Microsoft has actually discontinued the program. It will probably keep working for a while longer, but eventually they'll turn off those servers and everything will stop working completely.
So I went looking for an alternative, and gave Cubby a go. In short, it's not ready for me yet, but that might be because it's still in beta.
The test collection was a set of videos on my two home PCs. I installed Cubby on both machines, set them to sync the folder and was pleased to see that they showed progress indicators for the files that were being copied. I left it overnight and came back in the morning to find one of the machines offline and the other one saying that everything was up to date, but my online storage was now full. I didn't want to store these files online, just sync between machines, so I fixed the settings, logged back in on the second machine and left them going again.
After work, the two machines both claim to be in sync, but contain different collections of files.
On the whole, I liked Cubby. The setup was clean and easy, adding folders was quick, though could have been clearer or more straightforward, and I liked the progress indicators as I said. But, interface aside, until it can handle the actual file sync operations smoothly, I can't recommend it for actual use.

PS - I still need something else.
PPS - I'll keep looking.
