Any chance that PostGres/PostGis will work with ArcSDE Personal Edition?

Well that maybe opens up the possibilities.  Call me a dreamer if you
want but what if you could do multi-master between a PostgreSQL/PostGIS
and SDE (on anything) using two stage commit with geotools as the basis
of a piece of middleware managing the connections.  Put
update/insert/delete triggers in both SDE/whatever and
PostgreSQL/PostGIS that call the "multi-master" middleware and all of a
sudden (well, after appropriate non trivial dev work) you've broken the
strangle hold of the SDE engine on your enterprise.  There would be
issues mapping data types (spatial and non-spatial) with different
definitions between the systems which would need to be managed.  I
imagine you can shoot this idea down fairly easily, but at least you'll
increase my understanding in doing so :-)
