You can, of course, because you can just pass the Interface costructor a
class.  Keep in mind that DC's way of doing interfaces in Zope is one
particular policy that you can take or leave irrigardless of how you use
the Interface package.

Yes, for those of you, I salute.  Also, if you can, right from the
beginning, write your code in one certain way (prose doc strings,
private methods begin with _, etc) then by all means, go for it.  For
trying to ply interfaces onto a system of code like Zope that was never
written with, uh, literate programming in mind, it is better, cleaner,
and more assertive to describe the interface seperately.

Also, defining the interface seperately keep the two things apart,
impementation and interface, and doesn't allow you to sneak in a new
method unless you also sneak it into the interface, thus making a
stronger "contract" with the user.
