Are ODA nodes prevented from being NFS servers?

I have a customer who inherited an ODA x5-2 and they would like to use some of the ODA storage on other servers. In other words, is there anything from Oracle *preventing* an ODA node from being an NFS server?

The datasheet for this appliance
<http://www.oracle.com/technetwork/database/database-appliance/documentation/oracle-database-appliance-ds-1867697.pdf> mentions "External NFS storage support" under the section for "STORAGE", which appears promising, but then there is a section entitled "Optional Storage Expansion" that cites...

/And, to expand storage outside of the appliance, external NFS
    storage is supported for online backups, data staging, or additional     database files.
/

...which indicates that ODA nodes can be an NFS clients, which is no big surprise, and a darned good idea.

Does anyone know if Oracle has removed or restricted the capability for an ODA node to be an NFS server?

Thanks in advance!
