Wi-Fi VARs - Most demanded services/products

As someone wanting to make a business of wi-fi as a Value Added
Reseller, I would greatly apprecate some input from vets who've been
doing it as to what are the most in-demand (and profitable) wi-fi
services/products.

I'd target small to medium businesses, SOHO, and high-end home users
who want to network servers to wi-fi appliances such as cameras and
audio appliances.

After brainstorming a service/products to offer customers, I've got a
list that's too big. I'd need to narrow it down and not try to be all
things to all people. So, I could use some input from anyone who's
been in the wi-fi business providing services/products b2b and b2c as
to where to focus.

Thanks for your assistance!
