Greg at Nodalpoint has compiled an analysis of the spread of Nova Spivack's artificial GoMeme (version 1), including visualisations of paths taken by the meme through different social groups. The XML and GraphViz data is available for download.
It seems that most of the analysis had to be conducted manually, due to mutations in formatting. There is already a lot of extra data to analyse as well: Google has 3740 results for the long GUID and 447 for the short version, while Feedster has 389 results for both (using a wildcard).
