Getting an external param into a userspace streams filter...

Hi Wez, everyone: Is there (or will there ever be) a good way to transmit an extra parameter into a php_user_filter around the time that oncreate() is called? I've run into a couple cases where it'd be incredibly useful (e.g. for filters that don't modify the stream, but do have side-effects). Is there a known technical reason why this would be difficult or impossible? If not, can I go ahead and submit a patch at some point? :) Thanks, - Dave dave@codewhore.org
