Google Desktop Search + BibTex?

I searched all the known web, but there is no BibTex index plugin for Google Desktop Search.

Second, I just wonder: With all the indexers out there (bundled with Lucene, Strigi, Aperture, GDS, ...) when will we see an abstraction framework for them? Possible a simple web service that returns for a URL such as localhost:1234\indexer\file=C:\mydir\myfile.ext an XML response with extracted metadata and textual content. This way one could separate the value creation on file format understanding from the value of efficiently indexing stuff. Maybe the user interface is then a major thir part. Today, all three parts (translating whatever to text, indexing text, UI) are always bundled. As a result, all desktop search engines still suck.
