I don't know about open source solutions for you, but I'm working on a SAAS startup that offers some of what you're looking for: http://www.dedicatedmaps.com./ (u/p = demo/demo)
It's essentially a google map behind a log in showing only your assets with access control and roles for your users. We put things on the map that are automated real time (via cell phone app, SPOT unit, satellite-based VMS, or marine AIS), automated non-real time (e.g. we periodically pull or push locations and inventory details from an external database), and decidedly manual (user places a marker on the map).
Our current customers are oil spill response companies (who are quite busy at the moment!) They have to keep track of things that rarely move--like thousands of pieces of gear spread out in staging areas waiting months or years between spills, to things that move quickly--like personnel and ships responding to a spill on a river with ship traffic. We even have a satellite-based unit that can be thrown into the oil to show its movement, say, down a river.
I'd be happy to chat with you about how it works if you're going to roll your own or are interested in the service.
