I've created a "semi-Traveller" setting called Million Stars.
Some aspects are the same, but some aspects, such as travel*, are rather different.
Here's a link: http://millionstars.wikia.com/wiki/Million_Stars_Wiki
Note: the wiki is empty as of yet. The main map for the setting is in a Hexographer file, but apparently my account here is not allowed to post attachments. The only person who appears to have noticed it as yet seems to be a spammer.
*bodies within a system are specified as separate hexes, with a system being the size of a small polity/a cluster. A jump between these takes 1 day. There are also portals along fixed routes which also take one day to use but travel longer distances.
