Terrific! I'm glad you are taking the lead on this. I'm interested in helping if I can. I've pulled several of the non-i18n patches out of AD13 but I haven't had time to test them properly or move on to the i18n code. I agree that it would be a shame to wait for 4.0 - it would be great if this could get into the codebase in time for 3.6.
