Is it better or more appropriate than rsync in certain use cases?

Better than rsync (over SSH):

  - You do not need an existing trust relationship (or trust on first use)
  - Easier to punch holes through NAT/firewalls
  - Easier for non-technical users
Worse than rsync (over SSH):

  - Multi-file support is poor (basically it .zips up everything before even starting to transfer)
  - Zero support for incremental transfers
  - Cannot reuse existing trust relationships (and thus cannot be used non-interactively)
  - Easier DoSed
  - 1/65536 chance of connection being hijacked (by default)
  - Higher CPU usage
