This is awesome, thanks!

Is it possible to get a dump of all the signatures in a particular key server?

BTW: Just as a side note, I am studying "web of trust" as a general
concept (hopefully to become part of a PhD).  There is also the "FOAF"
web of trust, which is bigger (say 100 million plus) but perhap not as
high quality as GPG.  Im also looking at the data in ... it might be an idea to try and map all the
different web of trusts on the internets and collate the data together
