It's been a while since I thought about Glimpse/WebGlimpse but
they might be of interest.  Once upon a time they were somewhere
near http://glimpse.cs.arizona.edu/ but much has changed since
they began - they alienated part of their audience when they
went from something resembling FOSS to a for-profit model and
have probably moved elsewhere in the meantime...
