Topic Sensitive TrustRank
Since TrustRank is topic-independent, it could place too much relevancy on topics that are overrepresented in the seed set of trusted sites. Thus you could use DMOZ or the Yahoo! Directory to help extend out the seeded sites to a broader array of sites and topically bias their TrustRank score based on the categories in which they are listed. You could then filter out the bottom half of trusted sites in each category to prevent too many spam sites from being selected as trust sources.
There is significant effort being placed on looking for ways to move the PageRank model to a model based upon trust and local communities.
