Thanks Tahitibob! This is a great app! It seems to work perfectly, including with recurring events both to and from Google Calendar.

I did notice that I can't add it to the "launcher" applet, to have it display on the tablet's home page, the same problem seems to exist for other programs too, notably those from the sgt-puzzles package. I don't know what the problem might be, and I don't see any similarities between the puzzles and erminig. Not a pressing issue at all, just thought it was worth a mention.
