This thread should get some outside attention, lol.
It would be useful for developers as a means of locking an app to a specific device to protect distribution of their apps.
I'm sure there is a way to read the IMEI. Editing it might require something completely different though.

I seem to remember software on other platforms used to use this for the type of purpose you were talking about. This is maybe why it requires a DBUS request to obtain the information. As stated earlier though, the OS library could be wrapped potentially though to obviscate this value though. Would have to be a low level call.

Nevermind.
In any event the Forum Nokia WiKi provides some additional information using other methods code117. Maybe that can help in your quest...

However it is loaded and potentially edited may require a completely different means of connection to the device as well...
I didn't think that editing this identifier was the what the OP was after. I could be wrong though.
Schemes to reasonably identify who is accessing a server or service for what ever reason is not a bad thing and has nothing to do with FOSS.

For getting a unique identifier for mobile programming the 2 best things are IMEI and IMSI.
The IMEI is the unique phone \ device identifier.
The IMSI is the unique subscriber (SIM) identifier
So if you want to lock to a device use the IMEI and if you want to lock to a user use the IMSI
I'm not sure how to get these in Maemo but would say it's possible

So, you can change the MAC but then you have also crippled your device.
Nice idea but MAC can be easily spoofed.[...]
How this works on the N900 I don't know.

Could someone confirm this?
import sysinfo
print sysinfo.imei()
