I'd say this is the wrong answer, this can be done alternativly as used 
to do
(pushing an encrypted .rar or .zip is exactly this use case with advantage,
there is no implicit malware impact ...)

for security reason exactly this way you mentioned must be forbidden;
there mustn't be a way pushing malware to a server,
which the server itself has no possibility to clean it ...

as I think this is a security hole, too.

now where is a REAL USEFUL use case?
