Vray 5 for 3dsmax and Vray for Blender CE: coexisting is possible?

Hi Chaos,
I know that Vray for Blender CE doesn’t have any technical support but I think that this is more related to the licensing.
With my IT colleagues we’re exploring all the ways to expose the PC in order to get the cloud license requested by Vray for Blender CE (VfB CE) but with no luck.
Are Chaos aware that could be some conflicts when there is installed a Vray 5 for 3dsmax with a localhost license manager (with an active and working inline license) and VfB CE on the same machine?
As the localhost is able to reach Chaos servers to get the online license (not the Cloud one as the Vray 5 didn’t come with that option at the time), why isn’t able to obtain the Cloud license of VfB CE?

Have you any tips I can share with my IT colleagues to make it fully working?
Thanks in advance.

EDIT: Adding some info. As by Chaos documentation and as I have 4 remote machines as renderslaves that can’t connect to the web, I think that migrate all 3dsmax licenses to cloud licenses is not a good solution, the remote machines will not be able to licensed.
