Great work and very cool!!!
A few (rather obvious) questions:
1. General idea for a release date?
Together with RC3. Sometime next week!
2. Is there a list of compatible components? What sorts of components are better candidates than others for successfully integrating with jReviews Everywhere?
It comes pre-configured, with plugins (for components that use them) and with a integration guide for: CB, Sobi2, Mosets Tree, Hot Property, Jomres, Zoom Gallery and Virtuemart.
Configuring a component requires entering some info on the Addon backend like table names, fields and a couple of queries. These components above have very different table configurations and it's working with all of them so I am confident it will work with many many more.
3. Cost for existing jReviews users?
Price will start at $25 and will be increased to $35 after the first x number of sales, to be announced at launch.
4. Will Everywhere have it's own configuration (e.g. number of stars, etc.) or will it only be able to inherit the settings as defined for the jReviews component?
Unfortunately no. I have yet to do this for jReviews categories, like you asked a while back, and when I get to that it will probably be the best time to add it to jReviewsEverywhere as well. Right now the things that are configurable for each component are:
* Rating criteria
* Review fields
* Template/css suffix (on a component basis, not component category like with content)
The component categories are setup in the addon, and each component category can have a different criteria assigned to it (like with content). The component's reviews are moderated in the jReviews component together with the content reviews.
