UDF is really a cool idea, but like M$ Outlook, is horrible when it doesn't work (yes, I'm saying Outlook would be almost good if it worked). From experience (I used to do phone tech support for CD writers), I would recommend against using UDF, especially considering beta drivers. I saw so called "production" products from Adaptec that were really bad (these things shipped; I supported them). There was something known as "over filling" a disc, at which point you would lose all data on that disc; _maybe_ you can get it back. Also, "automagically in recent windows versions" is correct. You must have UDF drivers on the system in order to read the disc. Now days this shouldn't be much of a problem, but realize that UDF is by no means iso9660. You will probably _not_ find DOS UDF drivers, and I don't know the status for Linux drivers. Win95 UDF drivers were at one time available from Adaptec (IIRC).
Best bet is probably to try the second session thing. You may have to burn the existing iso first without closing the disc. I don't know; I've only burned single session with cdrecord. The more I think about it, the more I'm convinced this approach should work. HTH -Cedar PS.
