Best practices for Python plugins

At CC, I'm working on a plugin to pull CC license metadata out of files in 
EOG and show it to the user.

I read (and actually contributed to) 
http://live.gnome.org/EyeOfGnome/Plugins , but that documentation only 
covers installing the Python plugins to one's $HOME.

Is it possible to install plugins on a system-wide basis?  I'm thinking 
it'd be swell to ship the plugin in the liblicense Debian package.  (I 
took a quick look at the code and it seems to only look in user's $HOMEs.)

If not, is that planned?  Pretty-please? (-:
