Those Nanniebots from the spring have been back in the news. Andy Pryke was able to take part in a supposed test of the system at Jim Wightman's place, and discovered that the replies it produced were identical to those from a much older AI called ALICE. He also offered to produce the source code, but was kiboshed by a (convenient?) power cut before he could load a CD he said contained it.
Thanks to Ray Girvan, Waxy, for keeping on the story. BTW, I lost the link to Ray's blog in a site recovery that went wrong in early May and I've only just realised - sorry.
