Different transport protocols (TCP and shared memory) are used.

I'd say that 'direct access' is somewhat confusing term, as it could
mean three different things: (a) local access (aka XNET, aka shared
memory transport), (b) embedded access (no transport is involved) or (c)
OS file-level access to the database.

They definitely can, as long as you run the latest FB build of the v2.x
series.

This is wrong impression.
