Matakishi is working on some scifi rules based on the Anarchy Online MMO, and he's shared some missions (scroll down a bit). The pdf is a bit sparse on the details compared to our typical Infinity missions, but it's a place to start.
The Assassination is pretty typical, but I like the Hijack mission fluff. You don't need to escort a pilot in, you need to tinker with the autopilot! Data Retrieval is a "search the possible locations" mission (could probably file the serial numbers off of the 302 mission in Paradiso). Extraction could be a little fun, depending on how many 'friends'/bodyguards you give the HVT. Infestation and Research are more or less the same mission. Go someplace with hostile 'wildlife' and shoot the wildlife.
