[NTG-context] How could a typesetting system be today?

[Maurí­cio]

Hi,

Just because I'm curious: how could a typesetting system like TeX
be if it was created today? I've tried google and wikipedia, and
all I found different from TeX is a system called 'Lout', but it
seems dead.

Does anyone knows about novel or interesting ideas that could be
used if we would write a new typesetting system from scratch?

Thanks for your thoughts,
Maurício
