No, we wil not be updating EOM. With each release of inDesign, it has taken about 2 man-months to get EOM working again, and we can't justify the effort. We'd rather put that much time into scripts to make kerning with FontLab less painful, and which can be maintained with much less effort. This is now supposed to happen in late 2005. In particular, I'd like to implement an optical kerning algorithm, to provide first pass kerning values.
EOM is supposed to work with ID 2. Yes, you can have more than one version of ID installed and working at the same time.
