Here is another alternative. KoPI has a working sync mechanism with DTM. It can read from the DTM database, write to it, recognize differences, etc. This developer is amazing, he has done all this within a few months (thekompany needs to hire him to fix their problems ). KoPI also has a Today like interface that reads the database and summarize upcoming events.
Well, I tried to look through the code to see if I could modify the current Today plug-ins to have the DTM capability. But, I am not that smart and have had no luck. Perhaps someone smarter than I can do it?
