You can do that.  It sounds like most of the nodes may be accessing this
httpd instance read-only.  If that will be the case, consider using
spectator mounts on some of the nodes so you don't have to create 10
individual journals.

We actually use it for several purposes.  For one, we keep our document
root on GFS, so when web content is modified, the new content is
immediately visible to all web servers.  For another, we have a
file-based session implementation on a GFS mount.

The only real limitations I know of have to do with applications which
are not cluster-aware, and performance of heavy read-write loads.
