A few thoughts. I, too, am not a legal expert or anything.
DISCLAIMER: The following is, indeed, only my personal conviction. I am in no way entitled to give legal advice, nor is this my job or something. If you want to be sure, get yourself legal advice on the matter first!
First, oxps from Oolite are derivative works of a derivative work. Namely, they are derivatives from Oolite which they need to function, and Oolite itself is a derivative from Elite.
RS/OSE is in that sense a derivative work of a derivative work of a derivative work. It is based on the oxps it takes apart and puts back together in a new context. A starwars.oxp would be the same, essentially.
1) Anything originally Oolite is licensed under a Creative Commons license.
I cite the wikipedia entry about it:
"All current licenses "require you to attribute the original author". You have to give attribution to "the best of your ability using the information available". Generally this implies the following:
* Include any copyright notices (if applicable). If the work itself contains any copyright notices placed there by the copyright holder, you must leave those notices intact, or reproduce them in a way that is reasonable to the medium in which you are re-publishing the work.
* Cite the author's name, screen name, or user ID, etc. If you are publishing on the Internet, it is nice to link that name to the person's profile page, if such a page exists.
* Cite the work's title or name, if such a thing exists. If you are publishing on the Internet, it is nice to link the name or title directly to the original work.
* Cite the specific CC license the work is under. If you are publishing on the Internet, it is nice if the license citation links to the license on the CC website.
* Mention if the work is a derivative work or adaptation, in addition to the above, you need to identify that your work is a derivative work i.e., “This is a Finnish translation of the [original work] by [author].” or “Screenplay based on [original work] by [author].”"
Please note that for any Creative Commons license it is not only allowed, but a
condition for its use, that anything created under this license is share-alike. Meaning that you have to credit the people who's stuff you are using, and must not claim that they condone your work (except they do so in written form), but
you are not allowed to forbid the usage of this material, as this would breach the share-alike condition!
So while it is nice to ask before you use something, you are by no means obligated to do so, and I in fact didn't do that for OSE because it would not even have been possible to get hold of all those people the meta-oxp is derived from. But I will, in the final version, credit any and all of them as a matter of of course.
2) Anything that is derived from a copyrighted work (star wars or trek ships, etc. etc.) can be used if it is used in an absolutely-no-money-charged fanproduct sort of way, and these things are not under the CC license for sure!
There are already star wars mods out there for the X - series for example, complete with worlds and Jedi etc., and they are usually left alone as long as no one starts to charge money for them and they stay pure fanproducts.
Perhaps there could be problems if a project got so big that it might infringe on the income of the original creators, but Oolite with its download numbers in the few thousands will not qualify for that I guess. It is much more likely that Oolite can be considered free advertising for the things that it presents as noncommercial fanthemes.
3) Last but not least: If anyone wants to take anything from RS/OSE, if it is from me or partially from me or derivative, by all means do so. You really don't even have to ask, and if you do, I will help you with whatever you want to achieve. This is a fan project, everyone is doing this in their spare time for the heck of it, and I guess none of us should forget that.
Methinks this is a rather accurate summary of the situation.

EDIT: @saint & Cmdr James
Oh, yeah, sorry, about the original question. The star wars ships were made available by someone who named himself "Azzameen" on the boards, and has last posted on the forums on the 9th March 2007 ...
You can try to drop him/her a PM here:
