Then it should be fine and RC should be ok with just doing any kind of 
detection, maybe even just based on the extension... If unknown files 
are sent as binary it will be offered as download, so it should not be a 
big deal...

And even using fileinfo might be a security risk for the server, as 
there have been security issues in that package as well :)

Best regards,
