[postgis-users] ArcGIS Mobile slightly off-topic question

If you are just updating attributes and they don't participate in any
of the fancy geodatabase stuff (domains, etc.), using Access SQL
should work.  If you are editing geometries or they are using the
geodatabase stuff, you will probably need/want to use the ESRI Python
module.
