Its going around. Here's a story about it:

I particularly like Jim Thompson's post on this:

Or there's this thread:

Touch wood I won't receive this letter myself, but I'm inclined to ignore it
if so. If Acacia really want to make a big deal about it, I suspect people
like Jim will be lining up to make it hard for them...

Subject: [m0n0wall-dev] Acacia Internet Access Redirection
Today I received an information packet from Acacia Technologies Group
informing me that I was in volation of their patent on "IAR" [1]. IAR is a
US Patent 6,226,677 [2]. That packet suggest that I must license their
technology or face legal action. Has anyone else received this same
extortion letter?
The claims the the patent text lead me to believe they don't have much to
stand on. If I read the abstract and claim one correctly then it doesn't
cover a system that doesn't change the destination address. Any solution
that uses the IPFW fwd [3] rule would not modify the destination address and
therefore does not meet claim 1. I'm I correct in my logic?
What are your takes on this matter?
