I'd be happy to set up an interactive Deli map on wurmonlinemaps.com. Basically I take the map dumps, tile them and code up a sweet map via Open Layers.
On top of the map tile layers are various vector layers. For Xanadu: Starter Deeds, Deeds, Canals/Tunnels, Bridges.. Also beta testing a "landmark" layer, with Guard Towers and labels for Bodies of Water.
The Xanadu data is stored on a Google Sheets spreadsheet, which makes community map management easy, share-able, instantly updated. I would set up the spreadsheet, and someone awesome from Deli (with a google account) would get perms and make the updates.
I realize this is very different from the map experience that you have at the moment. It can get better! Check out the Xanadu map: http://wurmonlinemaps.com/xanadu
Someone give my a PM if there's interest.
