I don't know there had been a similar coding effort by someone for shogi
in Japan. But I think the delay of building shogi database comparing 
with
chess has invited us to use GUI instead of depending upon the coding 
system 
like ECO.

Let me give you an example. Please go to the following page.
http://yakan.flatz.jp/chokyokumen/search.php

There is an empty shogi board on the page. Please place black's King
on 9i and White's King on 9a and Rook on 4b. Then push the button above
the white's piece table. You will get 20 positions with K on 9a and 9i 
and
R on 4b which is both Anaguma and Shikenbisha(4th file Rook) on the 
right
side of the page. This is a trial sample of "Chou Kyokumen" which I 
think
is a webtop position database. The way of searching a position is almost 

the same as "Kifu Data 200X" sold by JSA. If you place more pieces on 
the
squares, you will get more precisely the positions you like to see.

So I don't think we have practical motivation to build a coding system 
like
ECO. But I may be wrong as I'm not a database designer/programmer.

I don't know very well. Only I know is the site says you can copy & 
paste 
the games one-by-one.

It's not for shogi, but reversi in Kurni. It was announced that it 
allows 
you to download monthly archives all in one file. Please refer to the 
following
Kurnik blog entry.
http://www.kurnik.org/blog/?20060925

I think you can ask Kurnik to let you do the same for shogi.
