So far, I have been working on the indexing part of Beacon, which is nearly complete. In the coming weeks, I will be running beacond (now index_server) as a service in the background so that I can find and squash whatever bugs remain in the code. For now, index_server is blazing fast, but that might be because the indexes I test against are just a few megabytes in size. From what I hear, though, CLucene can easily handle indexes which are several gigabytes in size without blinking an eye, so speed might not be an issue as the indexes grow. Anyway, any potential performance bottlenecks will only show themselves once people start using index_server regularly.
