From previous discussions with another Sync system they told me they might consider joining the federation if security and virusscanning is something that was being considered. Well it is, in this feature request I'll add (optional) virusscanning:
-Add a clamav scanner in the installer as an optional service
- build a virusscanning-on-upload service (that ties in to the "forbidden uploads" system
- expose the "this server has a virusscanner" variable, so that other servers know and decide whether they want to sync with this server.
