Hi,
I've just listened to a presentation at WordCamp Gdynia.

The prelection opened new doors in my brain and I thought that maybe it would be possible to use Playground to create something like a standalone multisite?

We have a lot of clients in our company on wordpress.com hosting, which does not support the Multisite option. So I thought that maybe it would be possible to connect several pages with Playground, mainly for content synchronization, cross-publishing, multisearch.
Thanks to this, clients could have extremely different pages on WordPress, and at the same time be connected by such a Playground hub.

What do you think about it?
