It can depend on the advertising clause for a start. The original UCB 
advertising clause can be removed (see 
<http://www.gnu.org/philosophy/bsd.html>). However other nutters have 
sometimes modified files, and put in their own advertising clause 
(short-sighted!).

As a result, we already have some files affected by the advertising clause 
in the net stack which is why the net stack doesn't have the eCos GPL on 
it. Given that, there's no reason why we can't include more code in 
principle although without advertising clause would be a lot better. The 
code would like the net stack not be GPL'd, but use the same header as the 
net stack (if one is going to be added).

I gather some people in the *BSD projects have been contacting original 
authors to get them to rescind the advertising clause on their files, so 
it's possible we could go back and check what they've come up with; but I 
don't know the state of that and it would take a little time to run through 
every affected file.
