I would strongly encourage you good folks to consider not only changing the name of the Home Edition (as per this thread), but also relax the allowed usage to include microenterprise and small businesses. The allowed number of users at four for the Home Edition pegs the demographic of the user whether a 'home' user or 'business' user. In either case, they are not likely to have the budget to afford enterprise-class products.
In today's world where the traditional employee/employer bond is severely challenged, it is getting increasingly difficult to distinguish a 'home' user from a 'business' user as there are many folks who would consider their home-based activity non-business even though they are finding ways to survive as self-employed folks. And many very small businesses often are the only way for people to make a living in marginalized communities. Access to software technologies such as SugarCRM and STARFACE can give us the edge to compete in today's world.
And remember, too, that the legions of contract temporary workers are 'stealth message-carriers' into the organizations who hire them on projects. I have often influenced a client by showing them how to use technologies that they are not aware of nor likely to have found on their own. So a relaxed approach to the Home (Community) Edition would allow your limited-user version to work better for you in generating more sales.
Finally, if you want to generate sales for the PBX edition -- at least in the speed of instant gratification world of the U.S. market -- you are going to need to add on-line eCommerce sales at your corporate site so that folks can purchase small numbers of affordable licenses. This provides a "stepping stone" sales process where folks and businesses can go from "kicking the tires" by evaluating the Home/Community Edition, then they purchase additional licenses as needed. Of course you could still use a distributor/VAR channel for large-volume sales and support, but please don't neglect us 'little guys.'
