From our current perspective, the proper placement of Telerik OpenAccess ORM is as a server side technology. However, that doesn't mean that the product should not be used for Windows 8 scenarios. You can still provide data to your client tiers using various kinds of web services. We have invested some efforts in automated service generation, to the extent that the new Add OpenAccess Service wizard can create and entire Data Transfer Objects layer for you in a few clicks, which is then fully extendable to match your needs.
In other words, it is just a matter of system architecture. Of course, our current point of view is subject to change in the future depending on your scenarios, so do not hesitate to provide your feedback.
