Topic: External file streams - do they work?

In reviewing some stuff in the PDF spec today, I came across something that
I had never noticed before that seems to address a common need - external
and/or remote images!

According to the PDF spec (1.3, pg. 35, table 3.4) ANY stream in a PDF file
(1.2 or later) can contain a /F key which allows you to specify that the
actual stream data resides in an external file (specified by a file
specification), including/potentially one specified by an http or ftp URL
(see section 3.10.4, pg 16).

Has anyone ever tried making one of these? Does Acrobat recognize them and
"do the right thing"? For local files only, or do URL's work?
