Probably not for me. I'd presume other companies like mine would use LDAP/AD internally and just sync to Google apps using this tool: https://support.google.com/a/answer/106368?hl=en
If this was a hosted LDAP-as-a-service solution that syncs with Google apps I'd be interested in using it at home. I also know of a couple of small companies that would love to not have any IT infrastructure in-house.
Good luck :)
