GXS is how
The GXS Trading Grid is the virtual evolution of nature!

Solution

When looking at the GXS Trading Grid it became clear, that it serves a lot of solutions on a business level, that nature tries to provide with tricks, like a wolf's howl, for this planet's inhabitats to survive.
Since the Trading Grid responds to such a large variety of demands, the answer to alot of big "business-hows" is: GXS is how! The similarity between the words "how" and "howl" closes the foodchain on this approach! : )
