Yes, you can do that too using regular Fedora initscripts. Warren is
just referring to libvirt's 'Virtual Network' capability which is
NAT based. You can read more about both options for network connectivity

Thank you so much for your answer.
The application to be developed is just a demonstrator of seamless wireless
mobility and video streaming services ubiquity, no commercial target. So, a=
s
we previously developed a desktop IPTV application in Java and now we need
to include ubiquity capabilities, is good to know what Moblin and Ubuntu
Mobile offers to port (or re-code) the application and add new features
(through wireless drivers information access and multimedia and UI
libraries).
It seems that this can be done more or less in a straight forward way once
the development environment is known. Anyway, if there is any closed access
to drivers or video streams in the Moblin/UME platform, please let me know
as they are essential for my development tasks.
If possible, I would prefer developing in Moblin/UME platform instead of
Windows CE, Symbian or iPhone OS. With Maemo platform (and maybe Android in
a near future), Moblin/UME seems the perfect platform to me, that's where m=
y
interest comes from.
Thank you again,
Javi
