Because the variable `org-src-source-file' is a bridge to pass info between two 
buffers "source buffer" and source block opened "dedicated buffer". So this 
variable must be global. Otherwise the "dedicated buffer" can't read it.

I tried this:

Put it into initialize function. This is the best way I can come up with.

Don't know which part you mean, I just insert the source file path into the 
link. About the final link is modified by bellowing `org-link-file-path-type' 
variable.
