I certainly see that objection. I don't have a strong opinion, I just 
hit on the idea of using custom links as a quick hack to do some inline 
semantic tagging I wanted, then thought it might be worth considering in 
the present discussion, as an alternative to complex new syntaxes.

Quibble: Note that =info:elisp= also means something rather different 
from =shell: ls *org=, =elisp: org-agenda=, or 
=elisp:(find-file-other-frame "Elisp.org")=.

Okay, so Org-babel might put these link types out of business (and 
anyway they unfailingly crash my Emacs 23 for the Mac). But currently 
they /are/ defined as Org links, even though "execute this code" does 
not mean "follow this link". So the double-bracket syntax seems to have 
a broader meaning.

Admittedly, though, all the currently defined link types mean "do 
something when clicked", which a =color:red= link does not.
