The other two, headless and Telnet support, I consider more complex for implementing in Tn5250j - but not impossible ;-) Because I don't have access to AS400 anymore (changed my job), I'm no more active in development. I would be happy, if you would contribute your work to Tn5250j (under the GPL). If you're interested you can get have access to the repository (assuming the other ones are fine with that). If so, the branch 'tn5250j-new-tabs-jse1.6' is the best starting point. I've also imported your sources to my Eclipse IDE and hit 'Run...'. Unluckily I've got an error, which I've attached to this email. I hope this helps you, tracking down the issue (if there's one).
