Generate TTF font at runtime and use it in TF

[artfabrique]

Is it possible to generate font at runtime, define it as Font class and then use it in text field?
for example:
1) user uploads table of custom letters (JPG)
2) as3 app. traces it to curves.
3) as3 app. creates Font class from it.
4) user can use it within a TextField

I believe that, technically, you could build a ttf file in a bytearray. You could then inject that into a pre-made swf bytearray as an embedded font. Then, load that swf bytearray, and access the font resource. However, there are a lot of points there that I'm not sure will work. Even if they did, it's certainly not trivial to build any of these bytearrays properly.
