You would probably mostly want to look at the action enablement code to
make sure the actions are not available unless the selected item is
managed. For many of the actions it probably already does this. This is
all done in the action classes in the UI plugin.

I think you are just scratching the surface though. I suspect the
FileModificationManager and all of the status and synchronize cache stuff
will be affected. You also have to come up with a way to handle the
decorators to be aware of this situation and present an alternate
decorator like CVS does.

You can probably checkout a "dummy" project using Subclipse so that it
gets connected to our team provider. Then close Eclipse and delete the
.svn metadata folders for the project and manually add in any managed sub
projects. Then restart the runtime, refresh the project and start dealing
with the problems. Once you have the major problems dealt with then you
can start tackling the UI of actually doing the checkout the way you
wanted.
