Hi,

back that up or in your experience have you been able to exploit this
type of configuration?

As long as it is set up correctly I think this would be fine.

However, part of "correctly", AFAIAC, is that both subnets are in the
same security domain - that is, if one is trusted, the other must be
as well.

but then... why should you segment at all... if the "security level" of the 
instances is the same?
the basis for segmentation (if not required per se per architecture guidance) 
usually is either different protection needs, different threat exposure or both.
if none of those applies no need to segment.
if one of those applies putting a trust boundary on a system like ESX which has 
so many flaws and weaknesses as for memory isolation/protection and stuff might 
be a bad idea...

my 0.02

thanks,

Enno
