Hi all,
Do you see any interest in the domain of femtocells?
this model, that will be sold in France, claims to be pluggable
(probably via ethernet) into nearly any ISP provided home router
(internet "box").
http://www.pcinpact.com/actu/news/65810-sfr-mobile-adsl-3g-femto.htm
Is it in any way comparable to the nanoBTS and other stuff you're
hacking nowadays ?

Of course.
There is already support for one in openbsc [1].

AFAIK this device is 3G only.
Since there is no 3G support in openbsc (yet), I am afraid there is
not much value in the device for openbsc at the moment.
Please don't take my statements as authoritative, I'm not a dev of the
project.
By the way, openbsc has it's own ML [2].
For a bit more information, see [4].
Kind regards,

Osmocom is actively working on a 2G femtocell (BTS).
3G femtocells (NodeB) uses an UMTS stack.
It is not a phone baseband. The openBSC list is more appropriate.
Also it's 3G, it's a bit different from GSM which osmocom is about
currently. There is no free implementation of a 3G stack yet.

This is the second version on the femtocell provided by this operator.
The first one was Ethernet only. This one mainly uses USB but also
provides an Ethernet port.
The limiting factor is that one needs a mobile phone subscription from
this operator to order the femtocell.
Getting such a device is not possible (hard) for everyone.

nanoBTS uses GSM while this femtocell uses 3G. The protocols are different.
Moreover, the architecture is also a bit different. Femtocell are more
then just transceivers.
But if you are interested, this femtocell (the first version) has
already been abused.
More information on http://femto.sec.t-labs.tu-berlin.de/ , or just ask
the involved team.
Good luck,
Kevin
