Catching up on some older posts... just wanted to clarify a few things.

This won't work (nor will any variation). The only foreign groups that
can be created are the system:authuser@* groups.
It is probably possible to add support for creating foreign groups like
user1@cell:group. I assume it doesn't already exist due to complexities
in some of the details, like choosing cell-specific IDs for them. Or
it's just a limit on the amount of "abuse" foreign users can deal to the

This should work. It also appears to work to just get a normal user to
create a user1:foo group, and then 'pts chown' it to the foreign user
(or just chown the hypothetical 'mygroup' to the foreign user directly).
This results in the group being renamed to user1@cell:foo, which you
could not otherwise create. Huh. This may a bug of some kind, but I
don't immediately see what it would break.

No, you can only specify groups and users for the cell in which the
directory resides. Even for foreign users; their entries exist in the
local pt database, too.
