i have a single Sun box with 2 users. Each user is assigned a hudson slave on the same machine.
i keep those two environments distinct because one is used for "CI builds" and the other to trigger "automated installation of our product". Keeping them separated allows me to do some damage control if, for example an automated installation came to get out of it's $WORKSPACE.

Now to my problem : after reverifying, it seems that it affects the slavestatus listener :

both point to the same machine (yet on different login account) with the same 3141 port. I suppose there is no way for it to know who's who.
