sounds to me like an addition that makes sense for certain situations. So 
having this available as an optional app would be great! Maybe it makes sense 
to handle upload and download limits likewise once you are on it.

No exactly. Quota limits are not applied transfer volume based, but 
statically. This is a traditional option from account management in a unix 
like environment: 

It limits the storage capacity a user account has available. Traditionally 
there were two limits: a hard and a soft quota. Hard meaning: operation fails, 
soft meaning it succeeds, however content is removed again automatically after 
a certain grace (and warning!) period. 
Such limit is obviously related to transfer volumes, since content has to be 
uploaded first. However it is not the same, since when the user frees storage 
capacity by removing content, then he is free to upload again. 
So the motivation for setting quotas is not bandwidth, but storage capacity.
