In order to package Tahoe for inclusion into Ubuntu, you'll need a few things:

1. The released zipfile (why do we use zip files?) for the Tahoe version you're updating to.
2. The existing package in Ubuntu. A simple apt-get source tahoe-lafs should do the trick.

Once you have those things, here's what you need to do:

1. Unpack the zipfile.
2. Create a tarball of the folder created from the zipfile. The tarball has a strict naming convention, which would be tahoe-lafs-<version>.orig.tar.gz. Create this with tar cvzf tahoe-lafs-<version>.orig.tar.gz allmydata...
3. Copy the debian/ folder from the existing package into the allmydata... folder
4. Change into the allmydata... folder.
5. dch -v <new-version>-0ubuntu1
6. Edit the changelog with the things that have been changed.
7. After everything is all hunky dory, run debuild -S -sa -k<gpg-key-id>
8. This should build you a nice package. The .dsc, .orig.tar.gz, .debian.tar.gz, and .changes files all need to be sent to a package sponsor.
