Usually each piece of hardware / software must be valided before going
to be plugged on the network. At this point, everything that follow
Q.931 implementation is ok to use, from the network point of view..

All network activities (like mass calling, mangle CLID, ...) are
regulated by telco acceptable terms and conditions and by counties law.
Using DISPLAY field to send "free" messages *could* be taken as wrong,
but I think this could change between countries or providers.

Right, and this could be a big issue, because the Neo / OpenMoko stack
gives access to the low level stuff.
Telco arent ready to open their minds, and this could be the easier
solution, ban Neo (Open) devices !

But I think this is a short term issue; let a provider understant the
power of OpenSources / Geeks, he will provide a nice structure where you
can dive into IN (Intelligent Network, from SS7), and you can probably
see very nice apps going out. If you can get a comercial company working
and selling apps with GSM inside, can you see the potential success ?

well said !
I'm pretty sure Neo will get a lot of ennemies, and hidding device (and
dev's) power will not make easier to adopt Neo from telco point of view.

Maybe it's time to get news from telco ? As Sean said, telco are a
target for mass market (september) .. so is there any feedbacks about
the acceptence level of that device and the Open idea stick with ?
