please see my use case where a locations serves global datasets for
other smaller locations.
Or the one with a test / "development" location.

moving/copying my file manager not a straightforward thing.
copying a vector for instance requires not to forget about the dbf
tables in their directory.

As everyone says: "at your own risk" and "no warranty" I would
appreciate to read the proper ways by a GRASS lead developer for the case:
1) location with common data to be reused in other locations.
2) location for testing new approaches before using the working locations

on-the-fly is not the topic here. I already asked this in a thread some
time ago and was educated about the GRASS way:

For displaying data from different locations I would like to try the
GRASS plugin of QGIS.
It's currently not working on my linux box.

Thanks for following-up,
