I'm playing around with OSCeleton and Processing and succesfully got to track skeletons and do stuff.
What I'm wondering is if there's any way to change the delay time a "lost_user" message is sent to Processing. This is taking so long for what I'm trying to achive, since i need to stop tracking a user as soon as he goes away from the screen, so I can accept another user's interaction. (imagine an installation where a lot of people wants to play with).
any help/tips would be really appreciated.

As far as I can tell from the OSCeleton's source and with my minimal experience with the kinect(I never used OSCeleton), there is no way to modify that code to do that. It seems to be a thing handled even lower, by the driver or by the kinect its self(?).
Yet you need not bind yourself with that, and I would suggest a couple of ways to bypass the problem if I understand properly.
First, the latest drivers and examples should have multi-user support, meaning you can just arrange who is your main user. From what I can tell from the source you do get an osc message in Processing when a new user is detected as well as an ID number. You can put each new user that arrives, into an arrayList and figure out a way to do things without depending on the latest user.
If you are still going for the user-after-user thing though, or I was mistaken about the multi-user support(which is mentioned nowhere in the README), you can check yourself whether a user has left the area. Although you can not get a definitive answer like that you can check for example, whether a specific joint or all joints of a user have moved in the last 10-20 osc messages received. That probably means storing the position of this joint in an 10-20 item array and continuously updating while also doing a check on whether the items are different. If all items in the array are the same, your user has not moved a bit and thus probably should not be taken to account.
Last but not least you can switch to other solutions. The one I used about a year ago was "Synapse for Kinect" which also seems stale now. The latest you can use is a Processing library called SimpleOpenNI which definitively have multi-user tracking and you won't need any intermediary programs running to give you the joints.
I hope this helps
