New, more realistic multi-hop network testbed

[Polychronis Ypodimatopoulos]

In the spirit of escalating collaboration/communication use cases to 
more realistic scenarios, I 'd like to propose creating the following 
multihop network testbed.

This testbed will involve about 70 nodes, but most are already deployed 
(about 50 nodes already exist at 1CC and 8 at the Media Lab). About 
10-12 new XOs are necessary to form the multi-hop network:

This testbed will be used to:

1) stress communication over the mesh network; this can be as large as a 
10-hop network spanning from my apartment (Eastgate) to a friend's 
apartment in Ashdown.

2) Test collaboration using Cerebro on a mixture of devices including 
XOs, x86 machines (Linux and Windows) and mobile phones. Cerebro runs on 
each one of those independently (including OpenMoko Freerunner), but 
this testbed could be used as a "backbone" network for devices that 
would otherwise be out of range (such as a mobile phone on one side of 
campus and a PC on the other).


Action items:
1) secure space (especially at Infinite Corridor) to house XOs.
2) setup and automate software updates over the network.
3) last but not least, get about 10-12 XOs from OLPC ;-)

Comments/additions are most welcome!
