There is an XPCOM to UNO bridge in OpenOffice CVS.
The full OpenOffice API is available through the bridge to any JavaScript applications.
Have a look at the README if you are interested and follow the “xpcom_uno module” thread on the UDK dev mailing list
There could be a number of interesting applications that would use this bridge.
Thanks to Daniel Boelzle and the udk team for this.
