Andre,
Thank you so much for your detailed reply.
I think you hit the nail on the head when you mentioned
social/individual/instructional capital.
I think fundamentally it will come down to a question of perceived risk.
A Cisco solution will be perceived as safer and our solution will be
perceived as risky. This is where I need to direct my efforts.
Regards,
Jason
