Could Pixelmad control up to 60 Universes of DMX?

[karamasov]

Hi

We´re planning on installing Catalyst 4 with the PixelMad plugin in a night club here in Norway.
I want PixelMad to control 30 ColorWeb LED nets. But I´m not sure how to set it up, connection-wise. The venue needs a cable plan, and since I´m a newbie, and nearing deadline, I would be most pleased with any assistance available!
I know naught about DMX universes or light jockey vernacular, and my mother tongue is Norwegian, so keep it simple if possible ;-)

Is this it: Mac G5 server --> Ethernet HUB --> ColorBlock PSUs --> ColorWeb LED nets?

This is the first of what will be a long stream of nOOb questions on this site, I fear.. ;-)
