That's another reason why I prefer the idea of a "ringworld" of the 
concept of the dysons sphere. Make a rim with walls on both side so that 
the atmosphere is kept inside and spin it. Solves at least the problem 
of atmosphere distribution and variable gravity which is an inherent 
problem of the concept of a spinning hollow sphere. AND you don't need 
that much materia to build it. But even Larry Niven (AFAIK a physician 
writing SciFi) had to introduce some sort of hyperdense material so that 
this small hull want fly apart.
