 ===== Overview =====
+It would be nice if NAV could offer an autodiscovery feature to make it even easier to maintain the IP devices
+you want NAV to monitor.
+We suggest this is added to the seed database tool.
+===== Input parameters =====
+The user should supply the following info:
+  * A snmp read community that should be used in the autodiscovery process (or possibly a list of communities)
+  * An optional snmp write community (or possibly list). :!: This should not be a part of the first version
+  * A prefix or a list of prefixes that defines the scope to search for new devices
+  * A seed router - i.e a router to get relevant arp data etc.
+  * A supplied orgid ?
+===== Algorithm =====
+  - retrieve all active arp records from the seed router that are within the search scope.
+  - for each of these IP addresses:
+    * if the IP address exists in NAV - skip
+    * if the address answers to SNMP with the given snmp read community - new device found!
+      * get system.syslocation: if meaningful use this as room in the bulk import format.
+      * set orgid to the supplied orgid
+      * decide category... hmmm. Morten?
+      * make new row to bulk file (format: roomid:ip:orgid:catid:ro )
+This is just an initial draft - should be elaborated/discussed
+===== API for snmp queries =====
+To avoid duplicating code from ipdevpoll, an API that does the relevant snmp queries should be offered by Morten.
