Re: [Haggle-arch] Haggle and GPRS

[James S. <jam...@ca...>]

Hi Salvatore.

Meng How Lim, the postdoc working at Intel on GPRS, didnt have much
luck with it.  He did get it working, and there should be an overview
of how he managed that in the root directory of the repository.  At
one stage he was starting the connection manually, I'm not sure if he
got further, because....

The main problem he found is that it is not possible in Windows Mobile
5 to have two simultaneous IP connectivities active, and once there
are connections on one, you cannot activate the ohter by binding to
the local IP address of that interface and then connecting out - the
connection will fail until all sockets are closed on the other
connectivity.

The GPRS, WiFi and USB connectivities (at least) would be affected by
this.   What it means is that if Haggle is not the only app running,
you're screwed.  Also one of the selling points of Haggle, i.e. using
multiple connectivities with different bandwidths/charging models and
doing this in a smart way per-task, is kind of crippled by the fact
that you only get to use one connectivity at a time.

I suggest that EU project partners focus on Linux phones only, until
Microsoft fixes this issue.   The alternative is to use GPRS and
Bluetooth, but Bluetooth is a bad replacemenet for WiFi since it takes
ages to inquire, it is slower, and it doesnt have the potential for
free, fast internet access through access points.
