Ed Burnette (of Eclipse in Action book fame) reports in his blog titled "Eclipse Powered" live from the world's first EclipseCon developer conference from Anaheim, Californa that IBM unveiled - hold your breath - XUL for the new Eclipse Powered Lotus Notes Client.

Ed writes:

Lots of good talks Wednesday, for example the Lotus Workplace Client technology merges portal technology with rich clients using "RCPML", a rich client markup language.

PS: If you have any links or more info about IBM's new XUL dialect, that is, RCPML, please let us know.
