Right.

If, along with that, we can keep legacy IPv4 applications running,  
which should be possible because there are only some 14M /24s in IPv4,  
we should be in good shape. No need to keep the latest stuff in the  
non-latest OSes or the non-latest stuff in the latest OSes running,  
except for that old IPv4 stuff that will be around for a good while.

Hm, I'd rather redownload 5 out of 10 files when my ISP craps out than  
10 out of 10. Partial deployment for multihoming is still useful.

This would be true for the scalability issue.
