Off the top of my head, I'm pretty sure that the AAT font format can  
support optical protrusion, and *fairly* sure that OpenType can do it  
as well. It's firstly a matter of font support (which is true in  
pdfTeX as well) and secondly a matter of XeTeX support, which would  
be tricky since it uses its own justification algorithm instead of  
ATSUI/<whatever it is Linux uses>.
