last job exit status (invisible when zero)
host:path in network friendly (ish) format
path shortening to last three components, plus subtle visual indication when this occurs (deliminating colon changes from host colour to directory colour)
- this shortening balances path context needs with space limitations. and is why the preceeding 'network friendly' format is "ish" :)
path colourisation to indicate whether $PWD is RW or not (not usually means RO, but may also mean 'directory does not exist')
count of background jobs (invisible if zero)
^ and $ reminder mnemonic for regex start/end line matching (I have a dyslexia about this!)
live time and load average (load gets dynamic colourisation also, but is invisible below threshold (set to 0.3 for me)
- for values of "live" that = "20 second refresh"
- this refresh ensures that an abandoned prompt will keep-alive a remote shell over dodgy NAT :)
current tty

here is my prompt:

warning: it's full of comments and code cruft, both from old revisions, and also future plans.
