Hi,
Would it be difficult, since piaware knows what version of dump1090 is running to update the link to the LAN webserver of the station to replace the localip/dump1090 when mutability version of dump1090 is detected?
Would probably easier to make it an user editable field on the personal stats page (like location / nearest airport)
Though it might be dangerous for some, maybe also add a check box to allow the url to be published (choice of not published, visible to logged in users, visible to everyone)
