For those Google Earth afficionados out there, have a look at this add-on:
http://globalais.net/dafifkml/ (click on the 'Initialize' link at the top of the page, and open what it prompts you to save).
It's basically a KML file of a heap of global DAFIF data (ie. airways, airports, navaids, FIRs, airspace structure etc), categorised by region. You can switch on the various regional overlays via the 'Places' pane in the sidebar, under Temporary Places -> DAFIF.
Enjoy, and apologies if this link has already been posted elsewhere.
