Just an FYI.
We also have had issues with a lot of software not supporting the C2 libraries. We bought 3 of them because they are a relatively good price for an LTO-3 unit, but quickly found out that a good bit of software can't communicate with them. I have spoken with Sun and the command set for the robot is completely different and because they are lower end units Sun and others were not bothering themselves with the developement. I ended up passing them on to our Linux and Windoze guys and went back to my L9 and L20. :(
