There are a number of other ways to use RDI besides rdi-share.  I
believe Cygnus produced an RDI<->GDB conversion daemon and it may still
be available from Red Hat; I know CodeSourcery also ships such a
beast:

We're only talking about the in-tree copy of rdi-share, which is a
different beast alltogether.  I don't even think it works with some
current RDI targets.
