There exists a 'test' clause in the mailcap syntax. To my knowledg
only NCSA Mosaic does not implement it (Look at the mailcap example
from Lynx!),  but that can be handled if the X11 entries come first!

So the mailcap could look like:
-------------------------------------------------------------------------
# Image viewers
image/*; xv %s;  test=test -n "$DISPLAY"
image/*; zgv %s; test=test -z "$DISPLAY"

# MPEG viewer:
video/mpeg; mpeg_play %s; test=test -n "$DISPLAY"
video/mpeg; vgamp %s; test=test -z "$DISPLAY"

# Quicktime viewer:
video/quicktime; xanim +Ae +Ss2 %s; test=test -n "$DISPLAY"

# AVI viewer:
video/x-msvideo; xanim +Ae +Ss2 %s; test=test -n "$DISPLAY"

# Audio player:
audio/basic;  auplay %s; test=test -n "$AUDIOSERVER"
audio/x-aiff; auplay %s; test=test -n "$AUDIOSERVER"
audio/x-mpeg; maplay %s
audio/x-pn-realaudio; raplayer %s; test=test -n "$DISPLAY"
audio/x-wav;  auplay %s; test=test -n "$AUDIOSERVER"

# Xing StreamWorks Audio/Video Viewer 
application/x-xdma; xnetview %s; test=test -n "$DISPLAY"

# MBONE Sessions
application/x-sd; sd-launch %s; test=test -n "$DISPLAY"

# Postscript viewer
application/postscript; ghostview -DSAFER %s; test=test -n "$DISPLAY"
application/postscript; gs -DSAFER %s; test=test -z "$DISPLAY"
--------------------------------------------------------------------------
