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.
