John
I took a look at your links.
I see that windev has inbuilt encryption of its dbf files. Shows it can be done, I guess. I also see proper inbuilt replication. Cool. Looks as if it does not use cdx, though. Not so cool.
Have you tried it?
Regards

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
