Well, if you work in an open source world (linux, freebsd, maybe cgywin),
I may have something for you. See:

http://www.stutzman.com/frank/flying/software/salsa

Taco is tool that given, say an airport identifier, batch downloads all
the IAPs from the NACO web side. Salsa does something simular,but does
it for the airport facilities directories.

These are perl based, command line tools that make use of pipes to some
tools commonly found on Linux/freeBSD systems like wget. As such, I
suspect they would be hard to port to other operating systems. Don't
know as I tend to avoid other operating systems if I have chance.

I wrote these things some months ago. Neither of them are particularly
polished, and there are a lot of tweeks that could be done to them.
My attention has wavered and I havn't done anything with them for a
while.

There is no external documentation for these things, but if you do
'taco --help' or 'salsa --help' there should be enough there to get
you going.
