You hit the nail on the head here, I can't afford to (nor do I want to) reach end users - that's why the system integrators are key, and I know they want a good solid solution to offer.

Thanks for putting a unique angle on your point, that helps reinforce my feeling on who I should be talking to. Its the same way I sell system architecture and development services - through designers who need it. Keeps me from dealing with end users who have no idea what I'm doing back there. (during the sales process at least) ;D
