Well, I'll say even back in the days of "we'll never have a stable NTFS library for linux!" did I believe that it isn't possible because of something. ;)
While I'm not an expert, I'm quite sure it can be done and probably a few 1000s people out there could spend an hour or two and have it running. Of course, until btsync gets a bit more popular (it's in the android play store now), we'll have to wait.
I'm VERY willing to put up money for the package to be added though. Open a kickstart or post the solution with a donate option. I'm in!
