I think I am beginning to understand. But I am not sure :)
I think the problem is that you constrain yourself by putting those 
20-30 resources only in the region visible at the beginning, whereas you 
have a potentially infinite space at your disposal.

What I suggest is : put less resources in this region. This way you'll 
get more "breathing space" for labels and all the stuff. When you have 
say 10 resources on screen at the max level of magnification, then move 
the camera slightly (for instance to the right), you'll then see empty 
space in which you can put more resources without creating a cluttered 

It is the same as working with a worksapce with scrollbars. When there 
are too much things in the region, you use the scrollbars to go to 
another (empty) region of the workspace where you can put new stuff. 
here we don't have scrollbars because the workspace is infinite, so it 
wouldn't make sense. But moving the camera does the same thing.

I'm not sure I'm making any sense here... Maybe it is fairly obvious and 
I'm not actually addressing your real problem. It is hard to describe 
this by e-mail.
