Front ends should *never* be replicated, only "back ends" (i.e., the
data tables). The reason for that is that, despite Microsoft's
claims to the contrary, replication of Access objects (forms,
reports, etc.) doesn't work reliably over the long term --
eventually the project ends up corrupted and is lost.

If there is no network at all, then you can't use replication in any
form, since the only way that any changes can be distributed between
replicas (whether front end or back end) is by connecting via a
network. Any other method (emailing files, floppy disks, CDs) will
result in the dreaded "dead replicas" (search this newsgroup on
Google Groups for the term and you'll find out all the problems they
cause), which lead to errors and corruption and eventual loss of a
replica set.
