I intent to package ndtpd. From README:
NDTPD is a server for accessing CD-ROM books with NDTP (Network Dictionary Transfer Protocol) on TCP. You can replace dserver with NDTPD. NDTPD can run on UNIX derived systems. It supports to access CD-ROM books of EB, EBG, EBXA, EBXA-C and EPWING formats. CD-ROM books of those formats are popular in Japan. Since CD-ROM books themseves are stands on the ISO 9660 format, you can mount the discs by the same way as other ISO 9660 discs. License: GNU GPL2 -- Susumu OSAWA
