the original DVI format already supports 4-byte character, what more Unicode-savviness do you need? Of course one should decide whether DVI should contain glyph indexes or Unicode codepoints.

Unless you mean by Unicode-savviness that one should have both glyph indexes and Unicode codepoints (I think that's what XeTeX is doing). A very bad approach since character and glyph correspondances are many-to-many.

On the other hand, if we use just glyph indexes in the DVI file then we can hardly do anything with it than print it (going to PDF will be difficult since the correspondance with characters is lost).

I'm looking for a what might be called a Unicode savvy Device Independent binary format.  And I'm looking for XeTeX and LuTeX to share code and ideas, when possible.
