[mythtv-users] Shared filesystem that looks different to different machines

This is immediately what I though too.

On server:
Create an export for /myth/music,
Create /myth/podcast-bob and /myth/podcast-jane directories and exports.

On Bob's client:
create /home/bob/music folder
mount /myth/music to /home/bob/music
mount /myth/podcast-bob, /home/bob/music/Podcast as desired.

I don't believe that NFS would have any issue with nesting a mount inside
another mount like this, after all the OS just treats it as another
filesystem and every linux system I have ever seen does this (/dev, /proc,
etc).

The one caveat would be that on the server, the data doesn't have the
proper structure.  This can be easily remedied by storing your data
elsewhere and mounting the folders to the appropriate location.  For
example: store your data in /home/shared/music, /home/shared/podcast-bob,
and /home/shared/podcast-jane.  Then on the server you can use normal
folder mounts, not NFS, to mount /home/shared/music to /myth/music and
/home/shared/podcast-bob to /myth/music/Podcasts.
