No not that Groovy. With the 10.1.3.3 release there is an important new feature for any of you Disco inferno's out there. You can now have BIP publish your Disco workbooks using templates, so its no longer a case of WYSIWYG in your Disco PDF output you can build templates to your hearts content. Whats more, its simple.
In a nutshell - use the BIP UI to pull in a workbook and create a report, use the template builder for Word to browse for your workbook, create and test the template then deploy back to the server et voila!
Ok, it was a small nut - thankfully the King of Disco himself, Abhinav has blogged the integration in his latest and greatest, there's pictures too which always makes life more interesting - http://oraclebi.blogspot.com/2007/08/bi-publisher-discoverer-integration.html
Enjoy and thanks Abhinav, you gotta teach me that 'do the hustle' thang sometime ... get down tonight!
