The RSS feeds are indeed a very intriguing addition. However, I'm still stumped about how to use them for the scanner - there's one per nation, so I'm gaining absolutely nothing by querying them all instead of querying the nation page and getting the endorsements directly.
Aurora (Endospider 4.0, in Drupal) will have archived endorsements, other information (gameplay stuff, influence, etc.), tracking of regional movements, automated updates... but it won't be done for a long time yet. To get this done fast, I can't even finish Endospider 3.0 (a "lite" version that will be far slimmer than Aurora), but will have to throw a dirty fix on the current mess and make Endospider 2.6.
