I run pcb on multiple arch's with the same $HOME so this would be most 
appreciated by me.

Here's another thought (sorry for coming late to the discussion). 
Should that directory be versioned (pcb version) too?

~/.pcb/hids/alpha-unknown-netbsd2.0/{20060822,1.99t}/
~/.pcb/hids/sparc-sun-solaris2.9/20060822/

I've done something like that with plugins for scilab where I know I may 
run more than one version of scilab on more than one architecture.
