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

1. The released tarball (.tar.gz from [http://tahoe-lafs.org/source/tahoe-lafs/releases/?C=M;O=D the releases directory]) 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 tarball.
2. Create a new tarball named `allmydata-tahoe-<version>.orig.tar.gz`, which is the same as the release tarball but with the `allmydata-tahoe-<version>` directory at its root. Create this with `tar cvzf allmydata-tahoe-<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.
