Okay I know very little about these things, but the fact that Access/JET MDB files are serverless (it's just a bunch of Windows dll's) in the same way as SQLite, and that JET implements row and table level locking means I guess it is possible. If it meant losing ACID compliance, then no, forget

MS Access (MDB files) use the Jet engine. Not every PC has the correct drivers, since jet has changed many times as Access evolved from version 2.0 thru 95, XP and 2003. Access is NOT ACID compliant, is limited in maximum database size, is limited to 255 connections.
