Stephen,
We are using “OpenThings” not “OpenWorld” but yes that’s the plan. https://openthings.io will be the parent site which has direct links and additonal marketing for all “Open-” products.
The usernames and passwords will be shared as well as user meta data allowing easy login across all sites using one account, correct. This is also going to allow us to integrate cloud sync with all the devices in the future.
Thanks!
