Discontinuous or Interrupted map projections?

Do any of the current open source GIS softwares support discontinous projection systems? E e.g. sinusoidal, dymaxion, butterfly, etc? 

If not, are there any affordable commercial ones that do (affordable meaning < $150)?

Upate: apparently Apparently it was a bad idea to lead with "sinusoidal", as that projection also has a single point non-interrupted form. Please note, theThe key word here is discontinuous or interrupted. Thanks.
