No, it's not.  There are sites online, that offer both as different
views for the same data.

Actually, I can see no reason, why your google-map code cannot be the
actual net-maps API with very little changes.

In many cases, it's just a question of URLs to call.

The maps do not differ too much, do they?
Both use Mercartor projection,
the x and y tile-coords are the same etc. 
For both, name services are available,
for both a HTML/JavaScript map can easily be included in web pages.
Both use the same way to zoom in and out (shifting, naturally).



Look at these two URLs for a tile:

Google:

  http://khm.google.com/vt/lbw/lyrs=m&hl=de&x=34535&s=&y=21537&z=16&s=Galile

OSM:

  http://b.tile.openstreetmap.org/16/34535/21537.png


Note the better Details, especially the bar ;) In forests the difference
is _much_ bigger.  And in areas with lot's of bars :)

Maybe I could be of any help.  I'm sure I could learn something.
