IMHO, what they need is to work on "ClearType for 3D" and/or "DirectWrite for 3D".
In the demo they use giant fonts, because text rendering sucks if you simply render text to a texture, then put that texture on a rotated plane in 3D. If that last stage was bypassed, e.g. when rendering text, the renderer would somehow know the rotation and distance, and draw the vector font directly into the screen pixels, they could get it crisp enough for most apps.
