I've recently been working on a suite of patches for four laptopists

and need to allow each patch to send messages to all the other patches

(for example, be able to send a bang to 3 other computers

simultaneously, and also be able to receive bangs from any of those

I've checked out netsend, however it seems that one is only able to

send messages to and receive from one destination at a time. I know

there must be a way that I can get all 4 laptops to send and receive

messages to and from each other over a wireless network

There are a couple of interesting java classes installed with Max. Look 

in the cycling74/java/help/ folder after the net.*.help files.

Apologies if this is a stupid question, but since all the computers are

macs, could I create a wireless network on one of the computers and have the

other 3 join that one? I have a router, but the less gear necessary is

better since there is already quite a bit involved in this project.

Personally, I wouldn't trust wireless for a performance if *all* messages
were critical.

I'll give it a shot and see how it works. All the computers would be

within close proximity to each other, and there won't be constant

streams of data being interchanged or anything. It's more like a bang

here or there. it might be reliable enough for my needs. Thanks for

please, if it works, could you keep me (us) informed - I actualy was 

willing to do so, but decided to go the easy route - with wires.

on one computer create an 'ad-hoc' network ie peer to peer. then get everyone to join that network. This avoids using a router. Then you could change the rts cts threshold on each computers network adapter card to a really low value to avoid collision of data packets. Also look into quality of service(Qos) settings if any. Depending on the WiFi card you might even be able to set the amount of retries before a corrupted packet will be dropped. I would use channel 1 or 12 since it will avoid the most overlapp of other wireless networks. You'll have to experiment with all this stuff to see what works best for you. Keep us in the loop.

err just tried to get to some of these settings on an OSX and XP machine... sorry none of that really appply. I've been working with linux lately and these things are all configurable in linux drivers... I'm sure there are some unix hacks for OSX. Anybody know off hand. It would be cool to be able to optimize a wireless card for performance purposes... I'm sure many would be interested.

There's been a fair amount of discussion on the list about the virtues

of wired versus wireless, esp. for performance.

Consensus seemed to be that wireless is slower--my experience bears

this out, particularly when doing installations in "noisy"

environments. But if you aren't sending a lot of data and rely on your

own private network (not the wireless network for some venue

I've done this without wires with MPG. We kept multiple laptops beat 

synchronized between two automobiles. The trick is to limit your 

data and build in methods for redundant information.

You can use [mxj net.local] to build a simple inferface for switching 

between the wired/unwired methods. This allows you to test the 

The part I always hate is having everyone call out their IP address 

to the person running the host machine while he/she types them in. I 

suppose I could use nethole to create a more automatic method.
