Wrt latex you might want to check out the microtype package, which wraps
around the new pdftex primitive. It allows to adjust tracking of sets of
fonts (e.g. all small-caps, or all tiny fonts or whatever), without
having to bother about adding any markup.

Yes, soul manages to retain kerning (if it succeeds at all, that is).
The new \letterspacefont primitive OTOH currently does not. This will be
fixed with the next pdftex version (and microtype, following it).
