I like it.
This would be a great tool to collect local information from people in a given area. You could use it to collect all kinds of information very inexpensively. Think about how much a store would save by setting these robots loose in the Mall to go around and query people about what they are looking for or provide directions to a known store. The basic interaction would be a very good source of information to analyze.
Great potential, plus it would provide a huge amount of entertainment for people stressed out by shopping.
Good find Cabe,
