AS/400?

so is the issue of connecting RoR to db2 on iseries going to be impossible? my workplace is 100% ibm, and i'd love to redo our customer load-tracking application in rails, but all our data is on as400 db2, and it's such a massive amount of data that replicating to a separate standalone db box would be cost-prohibitive.

Here is IBM's formal project on rubyforge for connecting to their databases including DB2 on IBMi (aka AS400, iSeries, System i, i5)

Another alternative, if I'm allowed to mention it here, is JRuby.. then you'd just need DB2 JDBC drivers.
