This might be old news but I just started getting some hits from this meta-search engine www.queryserver.com. I'm not affiliated with it, but I thought it was interesting.
I did some test web searches and it seems to produce some nice clustering results like Vivisimo. Looks like lots of people are developing clustering.

Oops forgot: Does anyone know anything about this?

Sorry about not getting to this sooner. I don't know anything about results clustering with meta engines. Sounds interesting though.
Seems, at least imho, that metas are only as good as what they can meta from - and that list has got to be pretty small...
