Yup. There are some people fooling with a more-Oracle-compatible parser
(eg, Oracle-style outer join syntax) but I fear that just scratches the
surface of trying to make something that's plug-compatible enough to
make Oracle users happy.
Still, having a SQL*Net listener would be a step forward, if anyone
cared to work on it.
