The ability to teleport between Kitely worlds and other Hypergrid enabled OpenSim grids was actually enabled on Sunday 18th, ahead of the official announcement, and saw a number of Kitely / OpenSim users putting the capability through its paces.
Announcing the move in an extensive blog post, Oren Hurvitz, Kitely co-founder and Vice President of R&D (and who is also an OpenSim core developer), said:
We have an important announcement: Kitely now supports the Hypergrid! Kitely users can visit other grids, and users from other grids can visit Kitely worlds. Kitely is the only OpenSim grid that supports the Hypergrid and also has strong content protections that prevent unauthorized items from leaving the grid.
The blog post itself explains how Kitely users can teleport from Kitely to other grids, how they can – if they wish – enable their Kitely worlds for Hypergrid access, and how other OpenSim users on hypergrid enabled grids can teleport to Kitely worlds.
Considerable length is given to the important matter of content protection and export permissions. This includes information on how items defined as No Export are protected from being physically removed from Kitely worlds either by Kitely users or those visiting from other Hypergrid enabled grids. To ensure content is fully protected, Kitely have also implemented changes to their Export World capability.
Given the in-depth extent of the Kitely announcement, I refer readers to that post for further details.
Overall, a long-waited move by Kitely, and congratulations to the team for achieving this milestone.
