I just heard from a developer that they used a windowless Open Office-X11 app to do some kind of 
mail-merge to print automatically, without interference of the user. He really hopes to get that same 
functionality in the Aqua version of Open Office. 

I would propose an enhancement that would go further, by exposing objects via Services and 
Applescript.

Services are parts of your own program that you expose to other programs. If you look under the 
services menu under the application name's menu, you might find some stuff over there. The nice thing 
about it is that you can very simpel expose functions in your application to do stuff for other apps. 

See: http://developer.apple.com/documentation/Cocoa/Conceptual/SysServices/index.html

I use them quite a lot, with (for instance wordservice.service from http://www.devon-
technologies.com/download/index.html, that gives you the possibility to capitalize words, sentence 
etc.

Making Open Office Applescriptable would do the same via a programming interface. The nice thing 
about it would be that this would make it possible to use OpenOffice via Automator to do all kind of 
nifty things.
