One suggestion:
Since many sources are available online it would be great if the bibliography could be linked to the source to allow full text search and annotation.
I wrote a library in java using lucene that accepts a url or a file from local disk and does two things
1) make a copy of the source file for later use in case the link is broken in future
2) extracts the text and store it in a database for full text search (supporting ps, pdf, doc, html, txt) to return a rated hit list containing the relevant paragraphs of the source and a bibtex export feature (not finished yet).
This would be a very handy feature for your package.
A very powerful site is http://citeseer.nj.nec.com/ you might know. But as far as I understood it searches only abstracts and keywords but serves the original file as well.
