[PD] scoping sends and receives

[shift8]

hi all - 

how hard would it be to code in an option for an additional arg to
[send] that gives it scope?  for example, [s foo] sends foo globaly.  

[s foo local] would make the send local to it's containg patch, and
subpatches, but not to the parent patch.  

[s foo patch] would make it local only to the containing patch, and not
subpatches or parent.  this make sense?
