Hi Dr Mody, the crew here is doing a good job but I thought I'd throw my hat in the ring.
The appointment scheduler is part of our patient portal, it would be difficult to embed it securely in an existing website. The schedule is behind the login page, so only existing patients who have a portal account can access it.
We do have practices who are paying to use the scheduling today, and many more in the pipeline.
What exactly do you mean by "test users"? If you'd like a more in-depth demo or have some specific questions, let us know, we'd be happy to oblige. Or, post them here, somebody may have already crossed that bridge!
