Hi again,
Great idea tim! Hopefully we can get this working, let us know how we can help!
The problem is that vbulletin is not free software. It is difficult to get help on this. But as far as i remember, i can have an additional test installation of vbulletin on my server. If any of you have some free time and serious enough to play with the available plugins to add java code support to them, i can install a test forum for you to play with it for some time.
But if i can not get help on this, i dont know when can i look at this issue because it has a low priority compared to other things to do.
