We are a small company and are very happy with BTSync. However, if you want tight admin control, you may have some issues. For example: If an employee leaves, we're not sure how to revoke privileges for them once they have access to the folder. So, I recommend very small companies use BTSync since it's easy and free. But if you're a larger company, you have probably outgrown BTSync and should get something like AeroFS.
