Hey guys, I have been really watching this project and collecting data. I was able to track some stuff down last night (when I should have been sleeping)
Aparently, Grub can be run server side...which gives your sites a kind of "priority" crawl. Jimmy announced that Wikia will launch in December, but there are already many engines using the Grub database..So it might be worth a trial. I am going to "attempt" to install it.
Anyhow you can read the dirt here in my Blog
