Thanks!
I'm not sure that's really doable using PyX. PyX is concentrated (in my understanding) on creating high-quality images - memory and runtime requirements are completely ignored for now. In order to render a text, PyX starts a TeX / LaTeX interpreter to write the text and then analyzes the output of TeX / LaTeX and translates it into the output format. Well, I just tried it: executing the example textbox.py and converting the resulting pdf to svg (using pdf2svg) needs on my machine 0.24s. So probably its fast enough for you (if you create many texts in series, it's not necessary to reload python, Pyx, Latex, ... such that the speed should increase...
