After more debating, the following comes up:

_ loading a .so (which would have to load libpython and so forth) at every
registry_check would mean extra memory usage for all gstreamer-based
application. So we need to avoid that.

We therefore need a way to check for other files without loading extra .so . A
way to do it would be to allow plugins to tell the registry that it should also
look for files:
_ with a given extension (ex:.py)
_ AND/OR some extra paths

If some file size/timestamp have changed, then the whole registry gets
reloaded. This *doesn't* mean the registry will look for gstreamer plugins in
more paths than the way it's currently configured, but it will be used to
figure out if it is 'dirty' or not.
Also, if system-wide python plugins are installed in $GST_PLUGINS_PATH/python ,
the registry will already be looking in that directory, since it goes into the
subdirectories of $GST_PLUGINS_PATH.
Another information the plugins could also give is environnement variables to
check for extra plugins path (ex : GST_PYTHON_PLUGINS_PATH).

I'll give a try at implementing that once I have the basic python plugin loader
working.

Comments welcome
