Microsoft AD is the ONLY reason many companies (Apple shops included) have Microsoft servers. People cannot imagine how disruptive is a fully operational Samba 4.0 AD for Microsoft. (like a fully operational space station with a planet destroying laser :p)

If you can offer AD as a service you could setup a tidy business, otherwise not very many people are going to look at this.

Small companies don't have the expertise, large companies can't afford the risk.
