In the future (perhaps Firebird 1.5) there will be also something called
Embedded Firebird. Instead of connecting to the server using a certain
database, you will be linking your application with a (set of) libraries
that access the database file for you. Of course, this is a one-user only
solution, as you can have no two application getting exlusive access on
a single file. This would be a very nice solution for your "remote"
employees.

As for Access being a RDBMS - NO!! Please no no no! (btw, the "R" part
of the current commercial implementations of RDBMSses is questionable).
Access is aimed at single-user access to a single file, with forms, queries
and
all other crap stored into a database file - you can write applications in
it, unlike
Firebird, which is "just" a database server application. Anything that looks
like
multi-user has been added to Access in a later stage, to overcome the gap
between single-user systems and multi-user Client/Server systems. In short:
patchwork.

Any (real) (R)DBMS is build from the ground up for multi-user access,
a single process writing/using one or more data-files, is ACID-compliant
(

pliant -
read a couple of those links ), supports different constraint types that
allow you to put logic in your database to tell the engine what the data
actually is (not on a human level) so that it can protect your data from
outside dangers (like people modifying your data directly, for example).
Security is also a part of this...
