Hi Philip,

We are basically are following the same lines. 

TeX is foremost a layout program based standard "printers"
methology.where the space character is white space and not a glyph.

We actually, do have to differentiate between the two in discussions.

The crux of of the problem is in (Xe)TeX's parsing algorithm. I never liked it
and personally I have many problems it.
