I guess no barriers, but careful testing on both the license and the 
quality sides (hinting, alignment, etc). I   remember taking care of 
adding the Freetype font engine in VTK a while back, and it took a 
fair amount of time to find a set of free fonts, with a compatible 
license. We ended up using some fonts contributed by URW specifically 
for Kitware, and some fonts contributed by Bitstream to the XFree86 
project. Since then, I've seen other free-font projects popping up 
(like the "Free UCS Outline Fonts"), but none of them looked complete 
enough to be worth replacing the current set of fonts we have in VTK 
(say, for example, they would not provide an italic version of a 
font, relying on the user to "slant" it manually, which is usually 
not satisfactory).

Now more scientific symbols would be nice, so I will keep an eye on 
this STIX project. For the moment, it does not seem like you can 
download any of the fonts.
