You would need to be running a local ADDE server which would know how
to read the MSG native format.  The ADDE server converts the native
MSG format into an ADDE Image object (same structure as an AREA file)
which is what the IDV knows how to read.  All the smarts are on the
server. So, unless you had OpenADDE running under windows and installed
Marianne's special servers, the IDV wouldn't know how to read the
local files.  The chooser sends commands off to the ADDE server
(which can be the localhost) and just reads the stream back from
port 112.
