An interesting question... from what I remember about Remus
(it's been a few years now since I looked at it), they
can't co-exist I think. To Remus, tmem is like a hidden
hypervisor-private local disk and the writes to it don't
get captured/replicated by Remus. I think this is fixable
but I don't think the fix would be easy.
But this is just a few seconds of thought, so I may be
all wrong.
