  \item RPC/IPC mechanism
  \item Takes its roots from BeOS and the OpenBinder project, which
    some of the current Android engineers worked on
  \item Adds remote object invocation capabilities to the Linux Kernel
  \item One of the very basic functionalities of Android. Without it,
    Android cannot work.
