Ultra cool stuff... Well, to build a data base will not be very difficult, as I have foreseen these requirements coming a few years ago :) All information is available on the APRS backbone, which all servers are connected to. It is just a matter of grepping the right messages, logging them and putting them into a database. I will have a look at the greps, and we can see later on where we put the data base. Pskmail.org is an option (but we have some problems with the hosting), and I would also be glad to give somebody an opportunity... In what form would you like to have the data?
