Mesh support very likely to miss Sugar 0.84

Concentrating on deployments risks "disrespecting" G1G1 purchasers.

My point is that in 2008 I had (with mesh) a working environment for 
collaborating in locations where there was no wifi access.  My post 
was a plea to "not throw out something that already works".

But mesh worked on the hardware I have, and can still (manually) be 
made to work with Joyride 2633.  Until I can (without replacing my 
XOs) see "network sharing options" working at Bald Cypress Mountain 
(far from civilization), to me that option does seem like vaporware.

Yes, two kids under a tree can communicate verbally.  But if they 
are cooperating on something tangible (text, images) - I seem to 
recall OLPC/Sugar saying there are advantages to "sharing" input 
entry and output journaling.

I believe that if collaboration *is* important to the user, he will 
learn what the available tools can be used for (including any 
potential distinction between "interacting with peers under a tree" 
vs. "interacting with resources through wifi").

My thoughts regarding automation -- it's 'Mother knows best' (which 
is the opposite of 'please, Mother - I'd rather do it myself').
