I don't know how much I personally will be able to help, but my research group at my University will be tackling the process of making a data upload / download (mostly upload) addon for a research grant we're doing. I'll be in over my head on most of the OSGi stuff, and it's been years since I did any real Java programming, but our on-staff Software Engineer will be helping out. So I can't commit to doing bug tracking yet, but if in the near future I find it's easier than I expected, I can try to help out
