Yet another repository layout question

I'm just starting a legacy app rewrite in python on Windows. And I'm
just starting to use subversion/tortoise hosted on my linux box's
Apache. I haven't previously used subversion or similar.

I'm having trouble deciding on a repository layout because it is really
four apps not one.

There is a core app in its own root directory which is where most of the
development takes place. The other three have their own root directories
with physical copies of the absolutely common code. All four have their
own unique modules on top of the common stuff.

You could think of it as all four sharing the same accounts receivable
but with separate market specific front-ends.

In the past I have moved them forward in sequence. The core app gets out
of beta first and when stable I copy the common code to another app root
then get that working and so on.

I'd like to keep the common stuff separately but I have to maintain
older versions of it in the other apps at least until I roll all the
users forward one app at a time.

What might be a useful repository layout? I think I'm stumped.

trunk
    coreApp (lots of common stuff plus unique bits)
    nextApp (ditto)
    thirdApp (ditto)
    lastApp (ditto)
branches
    ?
tags
    ?

I have read Chapter 5, Adding Projects (Choosing a repository layout)

Any ideas gratefully accepted.

TIA

Mike
