Is There A "Blog" Software That Does This? Help!

I'm new here, but I hope that doesn't stop some of the very helpful people here from helping me out. I've been a long time reader of the forum, but just joined recently...anyway, here is my question.

I'm looking for a software that does the following:

I input a list of sites that allow users to create their own blogs. Hopefully you know what I'm talking about. Sites that are running the wordpress plug-in that allows other users to sign-up and create their own blog. So I would then list all the wp-signup.php sites I want to create a username and blog at -

(I.E. - http://blogs.conceptmapping.org/wp-signup.php
etc.
etc.
etc.)

Then the software would auto-sign up at all the blogs I listed

And then I could write a spinnable article and then the software would submit that article (a different variation each time) to each of the blogs that are in the list.

Does anybody know of a software that does this?

Wordpress Multiuser (WPMU) + blogslammer (which allows spinning) is a possible combination.

You could also use Link Farm Evolution - it does exactly that - blog creation and management under one roof (and it works really good too).

Thanks to both of you guys, I appreciate the help. I'm just going to have to find something a little less expensive than LFE at the moment. Maybe when I get my next yourclick check I'll give it a go.
