In a recently translated Q&A with Akamatsu, it was recently revealed that Negima (as theorized for some time) is set in the same world as the Love Hina series. Also, two background figures in a flashback were Motoko and her sister.
Though that those who are more into Love Hina than Negima might be interested in this piece of info.
