Hi,
I don't know of anyone who has tried this approach for XBee I'm afraid. I guess you're looking at the Google repository for HAH Livebox code and so it might be worth posting your questions on the DBZoo forum re xap-livebox.ini ... but the content you have identified looks appropriate.
Do you have a HAH LiveBox ?

Yes , it looks like Patrick's website is down again ( patrick.lidstone.net ) . Is there something specific you were after ? .. I have a feeling there are backups of most of his code.. or an email to him should work .
cheers Kevin
