The saving of OARs and IARs is really such a foreign thing to many in closed grids, most in them do not have any clue what the questions are, much less how it frees them in so many regards.
Though I am primarily a proponent of free opensim, Kitely, as a commercial grid, offers tons of eye-opening and transparent information on the subject, and offers some excellent web-based tools for using them easily.
Their forums are a very good resource and one of the owners is a core OS code contributor-))

Not to mention the pricing is more in line with current trends in such matters and everyone gets a free limited use region to use to "get their feet wet".
