Running all machines, I dunno.  I do dual-boot Debian and GuixSD with
them sharing the same user profile and store.  On Debian, I bind-mount
some directories from GuixSD's root partition.  From /etc/fstab:

UUID=d9cc11f0-e548-4526-a541-4f631a10b73c /mnt/guix/      ext4    defaults        0       2
/mnt/guix/var/guix    /var/guix           none            defaults,bind           0       0
/mnt/guix/gnu    /gnu                     none            defaults,bind           0       0

Then /home/ is shared (and luks encrypted) on both distros.  It works
fine.

If you want to do "same profile and store across all things" Ricardo
Wurmus does some wild things using NFS.
