[Liverpool] Idea for talk for next month

[Sebastian Arcus]

Just while I'm thinking of it - one possible idea for a topic for next 
month's meeting. Not exactly Linux per se - but maybe we can have a 
dispensation this time :-) Wireless mesh networking. I've seen it 
mentioned here and there for a good while, but just never really got 
round to look into it properly - as I haven't needed it so far. Instead 
of an ultra in-depth presentation, or a hands-on technical one, it would 
be useful to have more of an overview of the topic - what is it, what 
does it do, roughly how does it do it, and when or why is it needed. 
Also, maybe which are the main options/protocols/models available - if 
that is the case.

Anyone already clued up on the topic please? :-)
