Hi dan!
I was hoping I could get a hold of you.

One problem with this is that you can't depend on multicast only. You
have to deal with both multicast _and_ unicast. Because of the nature
of wireless networks, you may be on a different channel than the person
sitting next to you. It's unclear whether or not multicast will
actually be routed correctly everywhere, and multicast has other
reliability issues (ie, multicast frames are not retried/acked in the
802.11 protocol level, they are just dropped much like UDP). So over
multicast, there needs to be some best-effort delivery protocol like the
MostlyReliablePipe implements. But the MRP protocol is really bad and
shouldn't be used.
That's why I wanted to chat with you. I want to use whatever subsystem
that Sugar will provide for the message passing, but it was my
understanding that sugar.p2p sucks right now and will be refactored/
replaced. I would be very interested in hearing about how it will look
in the future.
Btw, I think we should try and tackle this for BTest-2. It's a bit of a
stopper for activities author to start using the mesh.
It's a good idea to start working on something like this. And remember
to keep it simple from the start and work out from there, otherwise it
may seem like a mountain to climb. Furthermore, it might be useful to
identify one or two use-cases to build the model around; pick an
activity or two that you would envision would use this library, and look
at everything the library does with respect to those activities (and the
kids using those activities!) needs and interactions.
I'm going to start with Sketch. :)
But there's a lot of architectural issues to get sorted first, as you
said before.
Feel free to take the sketch code (which is currently in sugar/tests/)
and move it out to his own module when you start to work on this.
