Vimage virtual networking and 7.0

[Julian Elischer]

In the future I am hoping to be able to use vimage in our products.
They are based at the moment on 6.1, but I can see in a year they will be based on 7.x.

Patches for 7.0 and vimage are currently available in perforce. 

What I would like to see is if there are any parts of that patch that
would allow us to make adding of vimage to 7.1 an easier task.

For example, Anything that would prevent vimage from
needing an API change that would prevent it from being added later.

I am quite disappointed that despite Marko's best efforts, we miss the 7.0
release but if it can be made nonintrusive enough I'd really like to see if it can get in 7.1.

Personally, if I were "god" I'd put it in now because it can be compiled out.
and it wouldn't be compiled by default.Maybe only just bits of it..
for sure I want the ability to have many routing tables.
and I'm not thrilled about the requirement to have my own patch sets for this and thus 
not allowing others to use this feature.
