Well, they would be shims that just implement the FreeBSD
API using Linux APIs and some glue, so I don't see why they
wouldn't or couldn't be GPL licensed. I'm assuming (perhaps
incorrectly) that Jeff's proposed Linux shims are BSD
licensed, so the converse should be doable as well.
But regardless, Jeff's already done the work, so they
should just get imported into FreeBSD someplace.
