The problem here lies not so much with ePub as with CSS. CSS2 is antique, but neither CSS3 nor XSL:FO have the capability to accommodate complex layout-driven designs.
Relatively complex kerning modifications such as optical margin alignment either require specific support in the User Agent (Reading System) or would require ePub to use a presentation scheme fully capable of scripting. The latter is very unlikely, but with growing mobile processor power it's possible we may see more sophisticated UA-based rendering appear in the future.
