I've been working on an exporter myself. Between work and other projects, it's been slow going, but I make a little more progress every couple of weeks or so
At this rate I should be done by the time all computers are holographic and the latest Blitz3D is called BlitZHoloDeck v3.1.
Although, now that there's seems to be a bit of interest, I'll see if I can get it finished sooner.
