[Cialug] Networking Isolation Granularity Question

[jim kraai]

So, with lots of consumer software out there phoning users' usage and
content back to the software publisher, what can we do where on the network
to kill streams of traffic?

Feel free to point it out if the way I'm framing the question is too
limited.

Here's an example:  The latest word on Adobe's Digital Editions 4 desktop
ebook reader is that they 'fixed' the problem where it was sending
unencrypted data on usage and file listings back to Adobe by encrypting the
traffic rather than not spying on their users.  (

So, what are some options to tell the OS to not let traffic from processes
that fit certain criteria (name?) access endpoints that fit certain
criteria?

Thanks!
