http://linux.slashdot.org/linux/06/07/10/121246.shtml says that IBM has Lotus Notes running in Java (on Eclipse!). Two readers commented that they've used the code, and it's uncomfortably bloated. I bet there's still a window of opportunity for Wine here. James Hawkins is fixing the wine bugs that keep Lotus Notes 6.5.3 demo from installing on Wine; if that's done before the Java version of Notes is released (in two weeks), and Notes on Wine becomes easy to set up and run, it's possible we'll get a wad of good publicity out of it...
