Yes, forwarding still happens.

And the mesh does scale quite well for sparse setups (its original
design). It also works quite well in dense setups (e.g. classrooms) in
that it allows reliable communication between about 15 nodes -- that's
about 13 more than we were able to do reliably with the other
infrastructure-free networking option (IBSS/ad hoc). of course,
classrooms of that size (that are additionally RF-space isolated from
other XOs) are not very common so we need other solutions there.
