Commercial web-based application?

Commercial web-based application?

Hello, I am a Zoho newbie and this is my first posting.

I have had several encouraging conversations with Zoho personnel, but would like to get a reality check from some outside developers. Has anyone deployed a commercial application via Zoho Creator?

Specifically, I am building a vertical market, subscription-based, small workgroup application. I need to ensure that subscribers can only see or interact with records from their workgroup. Subscribers will sign up and log in via my web site.

Obviously the choice of web platform is a critical one. I would appreciate any cautionary tales from the trenches... I know what the upside is of using ZC; am looking to hear about challenges/problems/frustrations, or -- as might be indicated by lack of existing forum discussion on this topic -- why ZC is not (yet) an appropriate platform for this sort of application.

Thanks in advance to anyone who is willing to take the time to share their experiences and/or opinions.
