I've been working on systems for storing and retrieving arbitrary text "chunks" of information (with metadata) for some time now; see http://www.InfoML.org/ http://www.InfoML.org/ for the main idea, and http://sourceforge.net/projects/infocardorgnizr/ http://sourceforge.net/projects/infocardorgnizr/ for a working Java program for idea capture (not connected to a browser, but I've been thinking in that direction for a while). I've got software using a notecard-and-desktop metaphor working, though nowhere near ready for outside users. I know this is somewhat distant from what you're proposing, but I thought you might find it of interest. Please feel free to get in touch.
