Brčko is likely to remain a one-off, but its postwar history can teach us about the viability of "shared" cities in countries riven by ethnic conflict.
In the past decade and a half, they have shared cities - New Orleans, around the time of Hurricane Katrina - and even a home, in Silverlake, California.
Expansion from eight original teams to 16 proved to be overambitious: when the NBA, the original owner of WNBA franchises, began to divest itself in 2002, selling the WNBA teams to the NBA clubs they shared cities with or to outside investors, those that couldn't attract buyers were folded.
The company is hoping that the new initiative, called "Shared Cities," will get adopted by local governments internationally.
Resources and support from government are declining across Europe for creative ventures but still there are differences across the continent that cannot be ignored, so it is great that projects like Shared Cities exist to address some of these.
On 13 October just before I left Hungary Mindspace launched their new Urban pop-up space in Budapest that will host a range of discussions and workshops to bring different thinkers and doers to the table over the next three years as part of the Shared Cities Creative Momentum* programme.
