Reuters made a short report on a femtocell demo organised by ip.access. Check it out here. (Thanks to Mr. Adnan Boustany from PicoChip for sending the link).
What I like the most about ip.access's approach is that they realised the importance of effective marketing to win customer confidence. In terms of technical performance and features I don't think they are far ahead or behind the other major femtocell developers. Nevertheless it seems their relentless marketing effort is paying off.
