I see this is still in the Beta stages. I hope you fix the square brackets "[]" problem as this hack is very promising.
I also think the option to add your own tag is a great idea, very cool indeed and that gives you the ability to advertise your site in the tag in links.
I have one sugestion though. Make the ed2k links so they open in the same browser window instead of a new browser window. By doing that you won't have to close a new browser window everytime to add a link from the board.
Also take a look here at this same ed2k code created for phpbb for some extra ideas that might prove useful. This hack has come a long way and is the best ed2k hack out there. I'm sure there is stuff in this below you can use.

## Author Notes:
## If you have already installed a ed2k hack (which you mostlikely will have)
## check the files mentioned below anyways and change it to this version of
## the hack. This is very important to ensure it will work properly, otherwise
## you might have weird problems.
## Change the line below that looks like this to have a different text:
## $t_ed2kinsert .= "<a href='javascript:addall()'>Add ".$t_ed2k_confirmed." links to ed2k client</a> ";
## You can for example leave away the number of files.
