We haven't yet tried the WFS-T approach (another item on my to-do list).  We don't have GeoServer implemented at this time.  As you've seen from me in the past, we are not allowed to have PostGIS (per IT department policy).  So those are my major restrictions.

Ah, right.  I recently noticed that the FeatureServer website has been
polished up, http://featureserver.org/ and that SpatialLite is now a
supported WFS-T backend.  This could be convenient for mobile or
offline connections as well.

My understanding is that sometimes the ESRI defaults don't make it
easy to implement OGC standards well, but that there is a way to
eventually do it (sometimes with hurdles or non-intuitive
requirements).  The OGC has a listing here,
