I see that Ericsson has jumped into the fray with a femto product. I haven't yet been offered a full briefing on this, but will most more as I find out.
This line in the release is intriguing: "it offers full integration with the radio macro layer. The same radio frequencies can be used both by the Home 3G Access Point frequency and the outdoor radio macro network allowing maximum usage of the scarce and expensive radio spectrum". I guess this means that some of the RF planning is simplified - although to what density of femto's is unclear, or whether the operator's existing macro network needs to be from Ericsson. Given that many of the femto's will also live "inside" a firewall embedded in a DSL/cable gateway, I'm also unclear as to how the management of this might work - unless it's the same operator's customised gateway box rather than a retail Linksys/D-Link/Brand-X one.
It also appears that O2 made encouraging noises about femto's last week at a press event. A couple of articles cover this - Peter Judge at Techworld mentioning an Ericsson device in his piece, but with a confusingly contradictory mention of an ip.access box in this one.
Separately, I notice that Ericsson announced an update to its IP-PBX range, including a "corporate telephony client" for smartphones. Unfortunately, it appears to only support devices from the company's part-owned SonyEricsson range. This is a huge mistake, and one which indicates how far out of touch Ericsson is on the realities of fixed-mobile convergence in the enterprise. Device choice is extremely unlikely to be made with PBX interoperability as the sole criterion, especially from such a small range of suitable products. It is notable that its IP-PBX peer Siemens now has generic support for Windows Mobile devices, while clearly Cisco and Avaya support Symbian S60, Windows and increasingly even Java/BREW.
