I don't know how popular it is, or how reliable, but there's a DIY approach that's apparently called "ghetto tubeless" or "redneck tubeless" that uses part of an innertube to seal the whole rim. The edge of the piece of tube is locked between the bead of the tire and the hook of the rim, so imperfections in the rim are not an issue.
Those of you who know my DIY tendencies will see right away why I am tempted to try this. But I haven't. Yet.
For more information, I suggest you google "ghetto tubeless." I watched a youtube video about it, and remain intrigued.
