[web2py] Is it safe to run to web2py instances on the same database?

[Jason (spot) Brower]

First, is it possible to use the same model for two applications.
Second, would there, be a way to run these two applications safely amongst
each other?
I am thinking about sociability among very large applications. For example
an internal editor application and the external viewers application.
