All correct :)

There are several problems with nested domains. The major one is: given 
a page id in the inner domain, should path be encoded as a path on the 
inner domain or outer domain?

I remember that nested domains feature was not really included to 
realurl in the beginning. But than the company, where I worked, had a 
website with such configuration and wanted to use realurl there. I spent 
complete two weeks on it and it worked more or less reliably but still 
not always right. I believe we had to rearrange some pages to make sure 
that there are no more than one nested domain.

Now I strongly believe that nested domains is a wrong thing. The same 
result can be made with shortcuts or mount points. It is a cleaner way 
and it removes ambiguity in url creation. In most cases there is no need 
at all for nested domains because nothing like permissions or tree 
conditions are used. People just make them because they can but 
technically it is a nightmare to encode and decode such configurations.

So this feature is not coming back. As a solution for existing projects, 
I have two:
- Don't update realurl. Version 1 still works.
- Move nested domains to separate levels and use mount points in the old 
locations. This should give you the same effect.
