As I understand, when FIREBIRD_LOCK is removed, the only "solution" for
multi-user access will be to add user to "firebird" group. One cannot do
that without administrative privilege.

Anyway, I call this "solution" because in such case users will be able
to step on each others toes. When you have a database file which is
owned by a user, and a lock owned by that user, and group has no access,
then only that user has access - and he can run multiple applications on
the same database simultaneously. It seems to me that removal of
FIREBIRD_LOCK will be the end of this feature. Is this true?

However, if both users are members of "firebird" group and group has r/w
access to database and lock, then users can corrupt the database if they
both access it at the same time. Is my understanding correct?

If you have "embedded" application, why would you need to "install" it.
You just unpack it to some directory in your $HOME and run it. With
Firebird 2.0 you don't even need to have "firebird" group on the system.
That's what I call "embedded" database.

Please note that this issue is not so much important to me personally,
but I believe Firebird can stand a very good chance in embedded area and
it would be a shame to lose some functionality we already have.
