They have been offering similar type services for a while and I use them for my companies.

They provide a compliance version for $1,500 a year (http://www.openside.co.nz/index.cfm/Services/Compliance_Plus)

and a Plus version for $275 a month (http://www.openside.co.nz/index.cfm/Services/index.cfm/Services)

With the new venture, we plan to use a Web 2.0 reseller model that cements in a partnership by providing revenue for all parties from day one.

The trick is to make your interface so good, that resellers simply have to sit up and take notice. We only have to be good at marketing the service to the resellers and can hence devote more time to product development (in theory).
