I saw this morning on Apocalypse 40k that Chapterhouse, on the heels of the relatively advantageous (to them) court decision has initiated a Kickstarter for army-specific defense walls.
It's a clever idea for those who don't relish aquilas on their Eldar, Tau, or Ork wargear. It's also an idea that was implemented by others before this Kickstarter.
