More specifically, it is then up to the 3rd party (non-OSS) developers
to clear the patents. It's not the PgSQL team's problem in this case
(assuming it's the case at all).

"Plausible Deniability" and all that jazz. There is another truism
though; "Ignorance of the law is no excuse". Besides, claiming ignorance
doesn't keep you out of the courts in the first place. The people who
would attack OSS applications generally have very, very deep pockets and
can run a project out of money before the trial was over. They could do
that non-the-less (SCO, hello?) but I still suggest NOT tempting fate.

It's unfortunate that this legal mess causes the developers more
headaches than they need, but it still can't be ignored, imho.

Heh, I'm not an American either, so I can't do anything but shake my
head (and be equally glad that my own personal OSS program is here in
Canada).

American industry wonders why they are losing so many IT positions...
It's such a difficult and unfriendly environment there for anyone but
the biggest companies. Far too litigious.
