OpenSockets and multiple stacks...?

There should be no such restrictions...

Presumably each computer in your network will have an IP address... So
you just have a list of IP addresses and a repeat loop that sends the
message out to the same port on each IP address in the list.

It'll take a bit of tweaking to get it all worked out, but there should
not be a reason why you can't do it.

Good luck.

Subject: OpenSockets and multiple stacks...?

Hello All...

Not sure if this is possible, but I'd like to be able to have a single
stack, let's call it the instructors stack, send out a text message to
multiple stacks all within a single classroom network all at one time.
The "multiple stacks" would be student stacks.


I have had a look at some of the sample stacks in the "User Spaces"
specifically the work that AlexTweedly has done with his "TCP and UDP"
stacks, but have yet to determine if sockets would work in a
implementation as i have described. I get the impression that sockets is
something that can only occur between two stacks, not between one and
many, or many to many.

Or, do sockets allow you to open multiple sockets in order to facilitate
mutliple connections to a single server stack?

What I would like to get to is a Revolution based system similar to a
classroom performance system (http://www.pearsonncs.com/cps/) but
utilizing laptops and the improved capabilities of Revolution.

Anyone have some suggestions?

Thanks in Advance!
