Neighboring femtocells

Dear Osmocom community, Does somebody have experience using multiple 3G femtocells connected to a single HNBGW? Do cell reselection and handover work properly? How did you configure it? Also, Osmocom (or Syscmocom?) used 3G networks at Congress 35c3. Were you using multiple femtocells? Were they connected to the same HNBGW? How did you configure them for cell reselection and handover to work smoothly? Thank you! Kind regards, Mykola
