calendar with multilingual path

Hi there,

what would be the best way to achieve multi lingual paths for the
calendar module (including intact language switcher) ?  I tried
viewfield, but the arguments don't seem to work correctly and also my
calendar block won't point to the correct calendar path.

E.g
calendar/2009-06
fr/calendrier/2009-06
nl/kalender/2009-06

Tnx,

Hans
