Hey Jac, that's fine. I have seen the plugin that you mentioned earlier, but I have no first-hand experience with it.
I was interested also, because to me there is no significant advantage to the end user, if you use a WordPress theme or plugin - it is just easier for the developer or site owner. In the past, I have reviewed a few stand alone products for a customer. However, nothing came of it, because of AVS issues at the time, so the customer scrapped the project. If you are interested, the product was called osDate, and iti s using the so called Smarty engine and templating system. (In the interest of full disclosure, I ahve no affiliation with them)
