BTW,
Does this broadcasting sended over gateways to over department for example?
So, if you want to check how many users to used one licence not only for one
localnet, but for many localnets. In practice entire localnet may have
subnets for each department.
If we have two departments connected by bridge, for example:
LocalNet 1 (Core Development): 192.168.1.0 (3 hosts used IntelliJ)
LocalNet 2 (Core Development): 192.168.2.0 (2 host used IntelliJ)
Also we have licence per 3 developers.
We may use IntelliJ for 5 developers with license for only 3 developers in
net configuration above.

Thanks!

Even more simple: if everybody has a plain personal firewall on his
desktop and tells him to not broadcast the message, 50 people can use
a single license concurrently.

Well, some license check is better than nothing !
What else could they do ?
Polling www.intelliJ.com with the license key checking in real-time whether
there's only one license used at a time ?
And if you cannot connect the net, you could not use IntelliJ IDEA ?
Or otherwise (that's the solution we've chosen for our webapp product)
define a license for a defined machine, identified by its hostname or IP
address. But in that case, you could not use your license on different
computers...
There are different approaches, but each has its own drawbacks, I guess.

The idea behind: it makes no difference how much effort you invest to
create a system to secure your application, often it can be avoided
with much less effort -- or the usability will be reduces
significantly (e.g. when starting up IDEA, I need to connect to the
internet with my modem -- esp. when EAP crashes each half hour).

It makes me remember one of my course in Security-Cryptography when I was a
student.
The weakest point of a secured system is the place where the attack will
happen.
That's why it doesn't really matter what the length of a cryptographic key
is, if there's a flaw in the protocol surrounding key exchange. Etc...
So the current system with broadcasting license information is sufficient.
No need to spend more time (and money) on that.

And if I go to another country with a laptop and want to use Idea. What
could I do if I do not have any internet access ? I think it's
impossible to ask people to be permanently on internet.
In fact it's impossible to have a perfect copy protection. Look
Microsoft, they probably spent a lot of money with their activation
system and continue to spend money for the callcenter needed, but the
system was cracked the day it was released ...

It will be better with Windows 6 since in this version to write in the
system directories you will ask if Microsoft is ok ...

I just put attention to normal situation, not for special hacking.
With some hack you may crash any security system :))
