this is a multiboot linux-box, and other OSs can't print remote ;-)

--> +--------+      questions:
    :        :\     =========
    :  ;-)   +-+    1)	is the "can't grab ... with bind"-error in the same
    :          :	context that you means with  "reserve=rfc1179" ?
    :          :    2)	is an other solution possible as my work arround
    :          :	without root permission for cupsd ?
    :          :    3)  exist a possibility to run the backend
    :          :        only for this remote LPD-queue as root ?
    :          :    4)  exist an event to decide to run the cupsd
    +----------+        as user or not ?
		    5)  where is defined, that the queue will be
		        stopped by cupsd ?
