Edit in Sublime

One feature I loved in Textmate was its ability to edit text in other programs. For example, if I was updating a wikipedia article, I would:

1) Place my cursor in the browser's form field
2) Click "Edit in Textmate" which opened the field's text in a new textmate file
3) After editing the text, saving the file forwarded the updated text back to the browser's form field.

This is mac specific, but would love to see something like this for sublime. 

I'm no mac dev, but does anyone know what it would take to build this for sublime?
