ON top of the fact that RVs do not take advantage of precompiled SQL, accessing a remote view (like accessing a local view) locks, for a brief period of time, the record in the dbc that holds the view definition, and a heavily accessed system will cause contention that cannot be easily trapped, and instead throws error 1709, and renders a form or procedure useless.

Not if you provide local/private DBC's.
