Using Multipe TeamCity Servers

Is there currently a way or are there plans to be able to use multipe TeamCity Servers to allow build dependencies to be triggered between them?

I am evaluating TeamCity and how it could work for my company, but we have multpile builds distributed across the globe.  For performance reasons it might be beneficial for us to run a server in multiple geographical areas but still have the dependency chain triggered across the servers.

thanks in advance.
