Actually the "OpenRadar" client is written in 100% Java - which
includes the visible parts of the ATC screen, network protocol
decoders, geodata readers (to load airfield layouts, sector data,
shorelines and the such). Indeed, pure Java, as you say, which runs
perfectly on every Java 1.6 runtime I've seen so far. Personally I
don't like Java applications (too much bad experience with commercial
admin-frontends) but I have to admit that this one is done really,
_really_ well.
The primary author is a little bit 'insisting' about "doing things
right"  :-)  Thus, having a pure Java abstraction layer to CERTI would
certainly be first choice.

Yup, I know about Portico, but adding the entire Portico RTI to the
game plus a CERTI bridge would make the entire thing a bit bloated and
a lot more complex. I suspect that our friendly primary author would
rather implement CERTI's wire protocol in Java himself than plugging
yet another beast into the queue.

Cheers,
        Martin.
