Duplicati principal Kenneth Skovhede took some pains to reply to my post 
at https://groups.google.com/forum/#!topic/duplicati/FSejerztk0c 
<https://groups.google.com/forum/#%21topic/duplicati/FSejerztk0c>, but I 
don't know enough to evaluate what he said.  I would be happy if someone 
here can chime in with greater authority about whether the Mono 
environment adds significant security risks.
