I've got a small issue left that hasn't been pointed out so far (or I 
overread it *s* ).

Someone mentioned he finds this feature useful to help his colleques to 
get a certain thing working. I agree totaly but this does mean both of 
them have to work as the same user logged into the system or else we do 
not only have to re-route the program but we also need to change the 
user id its running with. In the end, it seems to me a bit more 
complicated than some thought at the beginning. Of course maybe i've 
missed something, or got some strange thoughts. If so, please correct me.

so thats been my 2 cents
