I plan to test a connection to a Progress OpenEdge database using a similar approach to HowtoConnectToMicrosoftSQLServerFromRailsOnLinux sometime in early 2006. – Ben Askins

Update: this won’t happen in a hurry, other projects have taken priority, but if someone else picks up the baton and runs with it please include your findings here – Ben, Feb 2006
