They do overall seem to show renewed interest in having low time between blocks, so if nothing else they might be indication it would be useful to rebase GeistGeld (15 second blocks) on new bitcoin code to bring GeistGeld up to date codewise.

Since GeistGeld can be merged mined alongside bitcoin it already provides, and has all along been providing, about as fast a block speed as can realistically be used, without needing to divert any hashing power away from bitcoin.
