I don't think CHIM is like being one with bacteria. With CHIM you are everything, everything is you, but if you do not retain your individuality you'll no longer exist. Essentially, you're the Godhead.
Chim is exactly like becoming one with the Force. You can still manifest yourself as a Force Ghost, but you are part of something bigger as well, you know?
Pro-sith tip, being one with the force is poppycock. You get stuck in the friggin afterlife, and if you were a goody-boy you're stuck in the most boring place ever, and if you were a righteously evil bastard you end up arbitrarily consigned to hell/chaos. The problem with the whole force ghost thing is that you still end up being trapped in the afterlife (obi-wan for example). That's why the sith try to do things like possessing people after death, the Afterlife svcks. Listen to hellmouth master thief, CHIM is so much more than the netherworld of the force. Hell, being "one with the force" is more like going into the dreamsleeve without the recycling part.
