Realm Works with Army Builder
 

It would be awesome to have compatibility on this level, for managing my tabletop battles campaigns as well as my pen and paper ones.

Any chance of this?

Funny you mention that as I just added a realm to for a Battlefleet Gothic/Warhammer 40K tournament my group is doing. It's a mere skeleton currently but what I've done is link in the HTML output from Army Builder into webpage snippets in Realmworks until something better presents itself.

The rest of RW works great for the fluff for our armies and for adding a narrative element to the grim dark battle raged... kitchen table.
