I don't think you'll find any issues, at least on the replica scenario
since the copied data is exactly the same for every brick in the cluster.
After all, Gluster only exports a directory content accross the network. I
don't really see how it could mess things up, especially if all you do is
reading the files on the exported directory.

I see the workflow basically as NFS or Samba. You can acces the exported
root and remove/add files from it without creating havock for the clients
except the usual "can't access xxx" if you remove/rename a file before the
client refreshes the directory listing.

I won't try such things though (not outside a test environment only) on a
distributed scenario since in that particular case, the files are splitted
in bits. Still, I think read only is always safe :-)
