Possible, but improbable (the private address space is fairly large, and most companies are very imaginatively using 10.[0-9], I have yet to see a 10.11. anywhere. 192.168 is indeed everywhere, but 172.16 is by far the rarest). You're setting yourself up for the exact same issue that Hamachi had, when it started using the 5/8 space for VPN - suddenly the block owner started using those addresses for outside purposes.

Well, sorry, but on the top of my mind, I have a client that uses 10.96.0.0/16 and another that uses the whole 172.16 subnet... I don't really see how I'm setting up for these kinds of problems as these devices only talk to my infra, but I'm on the other way avoiding a lot of problems.
