And they recommend this one

which looks possible although same issues potentially as you raise, Patrick
can't tell if it has PIP

Good luck with that mini-stereo mic preamp thing. There was one made by Andrea Electronics, which was supposed to be relatively clean. I think this is it. http://www.soundprofessionals.com/cgi-bin/gold/item/ANDREA-USB-SA This thing makes lots of noise about noise reduction, though I expect it's the same noise reduction you see on Intel and Realtek chips, which can easily not be used. Of course, you'll have to be careful with mini plugs when you involve earth ground. Something like that should be much less an issue with a portable configuration.
I can tell you from experience that the Griffin iMic, which has a stereo mic input, and costs about the same, is very noisy. Don't bother.

and here's the pi setup in london camberwell with icicle usb interface and the disk image from gregoire our audio still stutters and periodically drops our for a few seconds - if that sounds familiar to anybody, please let us know
what streaming software do you use? darkice seems to perform with about 30-50% load on the PI without glitches, if the network is reliable. so plenty of resources available, e.g. for a webserver ;)
That is about the amount of cpu usage reported with the PureData patch we have been trying. The network works fine for all kinds of stuff, so I don't think that's the problem. I think maybe there are some settings in the Alsa Mixer or the patch which need fine tuning.. will need some more time
i've made a cheap remote control for the PI, so that i can switch on/off streaming, reboot etc. from a smartphone web-app. it uses openvpn, ssh and phpseclib to establish a sort of console for selected commands (stream start/stop, poweroff, reboot etc.) along with the builtin hardware watchdog of the PI that should give a quite reliable unit. to test...
what i'm really looking for is a mini stereo usb preamp that supports plugin-power, so that you can connect a pair of electrets like the primo, wm61a, okm etc.
same here
recorders like the Olympus LS5 or zoom H2 work OK, but make the setup rather expensive.
exactly - whereas apart from that, esp with wifi and/or 3G, this has the makings of a cost effective solution.
