[PLUG] Reality collides with Linux worldview

I've posted before (here and elsewhere) about an underlying problem -
concept of users, groups, and permissions. I'm also considering the idea
that at some level the underlying cause(ww?) is linguistic rather than
technological (that will be for a USENET language forum).
Right now I have a discrete application problem requiring a solution
using current technology.
The ENVIRONMENT is a laptop with multiple installs of Debian Jessie
using MATE desktop whose purpose is experimentally determining an
optimal configuration.
I wish to have a partition set up in such a manner that ALL users of
*ANY* installed OS will have totally unfettered access.
My original solution was to use a fstab entry of:
UUID=E90C-65B4 /media/common vfat auto,exec,rw,flush,umask=000 0 0
(vfat specified as solution will also be used on a machine with WinXP)
The first problem problem was when copying a file *TO* that partition,
the "allow execution flag" was automatically set.
A suggested solution was to use umask=111. That, for un-understood
reasons, prevented deleting any file already there or copying new files
to that partition.
I did notice one other aberration when using umask=000.
When copying a file whose owner was 'richard' of group 'richard' to that
partition, the owner was *AUTOmagically* changed 'root' of group 'root'.
That suggest a form of solution which I have no idea of how to implement
- or even if it could be implemented.
Can fstab cause the partition's owner to 'universal' of group 'universe'?
NOTE BENE: spelling of 'universal'/'universe' intentional.
The intention being that *all* users would *AUTOmagically* be members of
group 'universe'. Would require attention to creating same gid
automatically.
Comments/suggestions please.
TIA
