If you grab the version from SVN, it should be fixed, although is still in need of some prettying.

Just read through all your links. Yay for open source. Brian is looking into incorporating those suggestions into the next release.
I whole heartedly agree, yea for open source!
I also agree it needs some prettying… The code prettying I did was just to allow me to find what I needed to fix that was broken, and to present a little more logically visually useful information (like the program name and moving its into the more logical sites area from settings).
Brian is doing a great job! My goal was to get a fully functional plugin working on our production sites.
However, that being accomplished (and knowing you and Brian are busy on other projects as well) I can volunteer some time to prettying up the code, line by line, if Brian would like it. I am (in theory) retired, been writing code since I worked for DARPA on ARPANET (about four decades) and have been playing with PHP since it was called Personal Home Page (about a decade and a half). I am new to WordPress (about 9 months) and currently have only about three dozen sites.
I do not know the ins and outs of how to get in touch with Brian, however, I am willing to help if he wants it. From my prospective, this is a vital plugin.
There’s already a free up to date plugin that does multi-network, as well as a premium plugin:
http://wordpress.org/extend/plugins/networks-for-wordpress/ – Free
http://wpebooks.com/networks/ – Premium
At least for the free one, ‘Networks for WordPress’, inquiring about the possibility of a collaboration should be worth your while. David Dean has been doing an outstanding job keeping his plugin up to date and supporting existing as well as prospective users.
