Unfortunately they just seem to drown in the big sea of Debian RFPs so I've been asking around on IRC and someone suggested that debian-science might be the right place to look for a package sponsor/maintainer since the tools are relevant for scientists and the lab equipment they use.
Both lxi-tools and liblxi are already included in Fedora/RHEL and are in a pretty good shape (full autotools support) and ready to be packaged.
If anyone here would be interested in becoming a Debian package maintainer for these two packages please let me know.
Thanks.
