Count me in as motivated. :-) 

As long as it's not too difficult to write the plugins. I'm definitely not a file format junkie since I just use whatever existing/available libs can provide.  But if it takes a little extra work to extend the file indexer capabilities at install time, then I'm down to help out by working on plugins for Bangarang 2.0 cycle.  Till then I'll address the potential duplication of data in the nepomuk store as a bugfix by giving Strigi an opportunity to index any opened file before Bangarang does.

peace and much respect,
Andrew Lake

P.S. Just a minor note that the duplication of functionality in this case is incidental since 
Bangarang, like any media player, will still need to be able to read metadata directly from files and 
will still need to be able to write directly to the nepomuk datastore for the in-context and non-extractable use cases.  I'll just need to add a branch the nepomukwriter code path to call the file indexer, hopefully extended via plugins, for technically extractable data.
