I just posted on this, but I didn't really address your original
question, so: I'm not aware of anything in the RFCs or other standards
which prohibits this. But then, I haven't gone looking, because...
It *can* be made to work in practice, for certain scenarios. For
example, if you're talking a web server, and you bind the "production"
site to 10.0.0.2 and the "administration" site to 10.0.0.1, and
configure policy routing (you said Linux, right?) to route
appropriately, it should work. It works because Apache can bind sites
to individual interfaces.
