My first impulse was to type "Boehringer Ingelheim" in Google. A completely different branch, but still an instant association in my mind. Could you try something different?
#105 and #108 are really nice, but can you just reduce it to 2 shadows in front of the X, I think the third is just a little too much. For printability and legibility could you try equally high fonts in "networks" and "consulting"? Keep in mind, a lot of social networking sites and also print usages give you trouble if the aspect ration is very wide, compared to the height.
#33 was almost there, it's just the color of "NET" and the grey is probably to light to make for good printability.
