If some competitor ran off with their code, companies like IBM and SGI
would be perfectly capable of suing their competitor.  As Linus has
observed, companies like IBM are prefectly capable of deciding whether
or not a lawsuit is in their interest, and aggressively pursuing legal
action when it's called for.

So I don't believe that compliance efforts are necessarily needed in
order for companies to feel comfortable donating large code bases such
as XFS or JFS.
