Both Jerry and pugdog are on dedicated servers, so it does work well for them. In terms of using it with virtual account, I don't think it will work very well...However, Gossamer Threads does provide services to create the rdf dump files that you can download and use in your directory.

My understanding is that the beta version of the spider script does suck up a lot of server resources (CPU, Memory, etc.).
