Searchable archives?

Does anyone know if there is a searchable archive of the
list available?

Yes, I know about http://www.crynwr.com/fsb/, but that is
not convenient for finding a past half-way remembered
discussion.  (This is sparked by a remembered comment from
someone who had audited a sample of patents and estimated
that something like 70% were probably invalid.  I would
like to track down who said that.)

If there isn't one, then I can always spider it for my own
personal use, but I didn't want to take that step while
there is a chance that what I want is already out there.

Thanks,
Ben
