The biggest challenge, Lynn, is always capital. In the industrial markets the sales cycles are long and you need to have the stamina to go all the way. It does not scale as fast as the consumer markets can scale from a revenue standpoint. How you get a lot done with a little is always a challenge when you try to provide solutions in the industrial space as a start-up.
From the standpoint of how we changed as we went along, I would say that when we started our path was that this market had matured enough that there was a nice ecosystem where we could play a role and form partnerships with other players to form the end-to-end solution. However, as we went along, we realized the ecosystem was just forming and not in place, so our customers are looking for us to provide more of the pieces in the chain than our vision was when we originally started.
