Hi wzab,
I also have the RFM70. Do you find it weird that the bank1 registers
switch from MSB to LSB as the first byte over spi?

Telit GPS/3G modems use Python scripting and it seems to work ok

Any kind of benchmarks on that? Memory and/or execution speed? I'm
actually quite a fan of Python, and use it for lots of scripting tasks
on my multicore, multi-GHz desktop, but it seems like an _enormous_
amount of bloat for an embedded system.
Unless, of course, embedded system means multicore, multi-GHz PC104 card.

My code using the py-spi module mentioned in the previous post is
available
in alt.sources (subject "Python code for RFM70 transceivers connected
as spidev",
news:<slrnidvosv.lsa.wzab@wzab.nasz.dom> ,
or http://groups.google.com/group/alt.sources/msg/d6e0525ca00f9801?dmode=source

I was looking for Python modules for embedded systems,
and I have found the following website:
http://elk.informatik.fh-augsburg.de/da/da-49/
In the subdirectory
http://elk.informatik.fh-augsburg.de/da/da-49/trees/pyap7k/lang/
there is a lot of GPL-ed code which may be used to interface Python
to different I/O interfaces in embedded systems.
I've managed to succesfully integrate the py-spi module with buildroot
and to use it for prototyping of spidev communicating code in my
AT91SAM9260 based board.
I hope, that the above info may be also useful for someone else...
