How can I meet and work with distributors?

My partner and I wrote a really great network appliance that is a great value-add and upsell to SAN solutions.

I would like to get it distributed through companies like CDW, trend-micro, etc.

What is the best way to meet with, or get in with distributors like these? All of them have forms and an address to send product demonstrations-- but it can't be that easy, can it?
