Okay some comments then.

I've been trying for many weeks to find a splitter for the headphone/mic input with no success - any pointers are welcome. My understanding is that the ones that are available for iPhones are a different pole order (happy to be corrected).

In general the userspace applications and audio processing I have played with (mostly gstreamer) are quite laggy - this doesn't mean it's a no-go just sub-optimal. There are other audio paths to try but gst is the path of least resistance for me.

Audio processing is pretty processor intense and in userspace I'm not sure if much (if anything at all) is offloaded onto the DSP.

We do not currently have any of LAPSDA plugins compiled or available for arm/maemo. The gst plugins available are fine (echo, volume, panorama, filters, limiter/expander etc) but aren't the sexy ones for guitar players (crunchy distortions, hi gain, big delays etc).

In short there looks to be a lot of work to do. I'd be really happy to be corrected on any of this.

Still, all said and done I'm by no means ruling it out completely. Just reiterating your 4 point challenge and suggesting that we don't have any quick wins on the list as far as I can see.

cheers

[Edit] Forgot to add that I'd had a quick attempt to see if I could get some usb input devices working with host mode. Mixed results and all short of a resounding success.
Zoom H4 enumerates but doesn't get hooked up by hid.
Alesis GuuitarLink (usd to jack adc built in) gets enumerated, recognized, hooked by hid but isn't exposed as a device through gstreamer. (incidently this is already quite laggy on my desktop machine where it does work).
In short the USB sode of things is great from a host mode perspective but taht's as far as it goes.
