Maps a global object id on any hyperwave server, even those you did not
connect to with <span class="function"><a href="function.hw-connect.html" class="function">hw_connect()</a></span>, onto a virtual object id.

This virtual object id can then be used as any other object id, e.g. to

Note: In order to use this function you will have to set the F_DISTRIBUTED
flag, which can currently only be set at compile time in hg_comm.c. It is
