[development] creating forward compatable modules?

[Tao Starbow]

So you are saying that Drupal acts like one big app, independent of the 
number of sites (I am assuming you mean 10,000 visitors vs 100 sites 
with 100 visitors)? That's really good to know. Is there a rule of thumb 
for 1 registered user = X anonymous users?
