Re:Databases - We're in the final stages of setting up our intranet using the ACS ported to Postgres. It's working great and we're really happy this far - a great system. The specs are (aolserver 3 beta6; postgreSQL 7 beta 3; ACS/pg 3.2.2). This circumvents the need to rely on either Oracle or Solid, and the online community support we've discoverd has been impressive.
