Yes, read only would be fine.

Why would it create two sockets for each file?

All that would be necessary was a record of which files were touched 
during the session, and only allow that to happen once.

Alternatively, only allow updates of files whose last modification time 
is greater than a set time interval. This wouldn't even need any state 
to be kept, as the data already exists in the store.
