Nothing stops you from maintaining a global cache shared by all shell processes.

I'd also like to point out that zsh's programmable completion does
allow you to override the default completion methods, which means you
could actually replace the default -tilde- context completion function
with one of your own choosing. I'm told that zsh is also superior to
bash in many other ways.
