One way would be to write the status to some file at the end of the remote build, then either read the status from that file (or possibly use the existence of the file as the status) in the next remote build project or pass it from the "driver" project to the next remote build project via the command-line.
Another option would be for all remote projects to share a global macros file on a network share (using one of the methods here [1] to load it at startup), and then update/use a global macro with the status to be passed between builds.
