That doesn't seem a problem at all.
The goal is only to interface the trace phone with wireshark trough gsmtap.

I never worked on wireshark but that seem a usefull skill.

good, I know a bit ISI too but not too much in detail(I was involved in the
port of SHR and freesmartphone to the nokia n900).
That skill can help a lot too.

I don't know which one of us has the higher chances to succeed, but since you
are willing to do it, and that you seem to have the required skills, and that
I can work on other things as well(for instance finish the port nuttx to the
calypso phones), I would say that you can take the phone assuming you really
work on it and I hope you'll succeed.
I wish you good luck.

And I've already two osmocomBB compatibles phone(the freerunner and the c155).
Altough I did not yet analyze the GSM protocol yet apart looking briefly at my
own gsm packets without understanding the details, I'm still learning how the
GSM protocol(Um and Abis) work(I only know the big picture so far) with the
online slides of Joachim Göller.
I'll also try to find out about all the other features of osmocombb, to look if
they are really usefull for development in the GSM protocol,and how to use
them legally in Europe.
So far I was concentrated on nuttx and only tried some of the osmocombb
features recently(like the gsmtap/wireshark integration on the master branch).
