I don’t see how the burden on cashiers is changed.
I had similar experiences with the earlier alpha/beta releases using a ton of CPU/RAM and having a ton of other issues, but lately it's been working quite well. I sync a lot of files, over 30GB, and Dropbox and Google Drive did a spectacularly poor job with that kind of load as well.
The iOS app for BTSync absolutely lets you browse your shares and download individual files. Otherwise I would not be able to use it.
My cloud server is a g1.small on GCE, and I run Sync inside Docker on that instance. The same server also runs a bunch of other crap, and it's far from resource constrained.
About once a year I went through the exercise of "let's try replacing Dropbox with something" and this time, with BTSync, I have been able to finally get rid of it, with the exception of a few mobile apps that rely on it.
I agree it could be more open, and I'm always on the lookout for a better solution, particularly one with similar encryption capabilities. If you haven't tried BTSync in a while, perhaps it's worth another look.
Sync still has room for improvement, but it does seem to be constantly improving.
