If you do a C API wrapper around the C++ bits you need, then you
should be able to use the C wrapper from FFI on either MRI or JRuby.

If you use rice, then it won't work on jruby at all.  Although, the
rice C++ api does look semi-sane, so it might be interesting to
implement support for it in JRuby - but its not going to happen this
week.
