Hello Moritz,
This support was recently added in MVAPICH2 1.9rc1.  You should be able to use
the RSH_CMD environment variable to complete your integration.

    Usage: ./configure [OPTION]... [VAR=VALUE]...

    To assign environment variables (e.g., CC, CFLAGS...), specify them as
    VAR=VALUE.  See below for descriptions of some of the useful variables.

    Defaults for the options are specified in brackets.
    ...
      RSH_CMD     path to rsh command
      SSH_CMD     path to ssh command
      ENV_CMD     path to env command
      DBG_CMD     path to debugger command
      XTERM_CMD   path to xterm command
      SHELL_CMD   path to shell command
      TOTALVIEW_CMD
                  path to totalview command
    ...
