Will the occupation in the center of all cities be like the shopping malls of suburbia, except instead of shopping for makeup or sneakers, you'll shop for new politics?  

New businesses will sprout up with services for people spending the night at the occupation. You could already see this at Zuccotti. The portable food vendors are there. You can get a nice lamb over rice. What other services will pop up? (Porta-potty vending? Meeting centers?) 

What other services will pop up?  

Porta-potty vending? Meeting centers? 

And maybe special facilities for General Assemblies. 

Is there any science fiction that anticipates occupations?
