[Orgmode] Looking for help linking to an org document on mac os x

[Anthony Lander]

Hi everyone,

I'd like to be able to link to an org document from other  
applications, and especially to a particular line or search term in a  
document. The idea is that I could, for example, put a link into an  
iCal entry, and when I click it, emacs would show the file and move  
the point to the correct location.

Basically, I'm trying to make something like a URL, but for org, that  
the OS would dispatch correctly. Something like org://path/to/some/ 
file:*search-term.

I've poked around quite a bit, but I can't figure out an easy way to  
do this. Does anyone have a suggestion?

Thanks,

  -Anthony
