The 'and' between these is what causes me heartburn.
The first half of the sentence is relatively easy, but as I mentioned,
your current office-net configs mean some changes will be required,
one way or another, to get this working if your offices are included.

The second half, I need to engineer around that our net cannot do
this in the short-medium term.  We're talking at least mid 5 figures
to get our net minimally routing IPv6; I need to check on card
compatibility issues.  I'm not sure if it will work without replacing
line cards.  This could take up to multiple 6 figures for the full
forklift.

Since I don't see that sort of money coming my way anytime soon,
we can work on finding some other way for now.

How to proceed?  Would you guys be able to tell me what machines
where will need v6 in the short-medium term?  I will try to engineer
it so adds/moves/changes will be fairly painless, but I need a
starting point.  Drop by my office anytime if you want to chat about
this stuff, too.

Yeah, my guess is you could survive without for a while.
I simply don't have the time to work on the DNS aspect, nor am
I the best/most knowledgeable in that area...

Thanks,
