Of course this approach will cause certain concepts to flow over.  Now
you have a single project that contains what (may be) multiple independent
projects that are related, but actually independant.  For example a number
of utilities all in the same package.  This means that things like searching
and refactoring will take the entire super project into consideration. Other
items like automatic compiler setting detection may be made more
complicated.

If the projects are truly independant, then you should likely create
separate
projects for each directory and then if you want a "unified view" project
you
could create an extra top level project and then using linked resources link
it to the top level directories.  

If it is just visual distinction you are looking for, then working sets can
also be used effectively to cut down the noise of having a lot of top level
projects rather than using project nesting.

Just a few thoughts ... your mileage will vary and I would encourage you to
try out all of the different options to get a feel for what works best in
your
scenario.

Hope this helps,
