Running programs such as vim and gdb require a pty device to attach to. We need to investigate how to properly handle this when executing these programs on a remote machine. The plan is to build a standalone prototype (i.e. outside of mesos) as a proof-of-concept for to how make this work properly. Once we have a good feel for it, we will back port it into Mesos and integrate it with the rest of the system.
Development is being done here: https://github.com/klueska-mesosphere/remote-pty
