Archive, batch processing

G'day,

It's beautiful spring weather here in Japan, and a young researcher's
thoughts turn to parsing.

I have a couple of questions:

(1) Is there an archive of mail to the lkb list?
    If so, where is it?
    If not, could  we archive it at the linguist-list?
    http://www.linguistlist.org/addlist.html

(2) Is it possible to pipe through the lkb?:

    cat input.txt pre-processor | lkb | post-processor | lkb

(3) Is the PET system publicly available?
