Can nginx modules read files from network connection?

Hello,
My first post, please excuse if this question is answered, I did not
find information with searches.

I am using flv module as basis for a download module that talks to
MySQL for authorization (filehash in URI checked against users’s session
cookie & timestamp for download permission in database).

For now files used are in the filesystem. But I cannot tell with my
limited knowledge yet whether nginx can also open files from network
(TCP/IP)? Is that also possible, or file systems only for now?

I am using 0.7.64 and 0.7.65 for production servers but if there is
something in development versions my boss is willing to consider using
those versions for our specific needs.

Best regards,
Gernot H.
