I cast my vote for GCS! Malte is right, using GCS will automatically endow us with the "open" aura, and will definitely get more mileage.
I know - I kept pumping up the importance of brand, and developing our own, but luck, oftentimes, plays an important part in getting traction.
Hitching our star to the GNU wagon methinks is also a valid strategy.
And if we want to develop our own unique brand, we can always create module names as Michael suggested.
Also, using GCS might help facilitate pushing to get the system as part of standard linux distributions.
I know we have a lot of Debian folks out there in the community, maybe they can package it up and submit it. Somebody doing SUSE and RedHat might help as well.
