GEEZ! I don't know why I keep posting on this topic, clearly nobody
bothers to read my email (grump grump grump). I said a couple of days ago:
I suppose it would be possible to do a nasty hack like prepend another
"njar:" onto the front of an njar url and see if we could trick the
njar protocol handler into unpacking then accessing the temp file
location it creates ....
So yeah, it might work, but I still think its a *hack* and unpacking on
deploy is simpler, centralized and foolproof.
Go back to bed Jules :-)
