Cool. Works fine with xlogo (on latest ship.2 build).
With xeyes, on the second start I get two colored icons, one of which
keeps pulsing. With xterm, I get the regular gray non-activity icon,
plus a pulsing one that won't stop. Apparently not even these basic X
programs use the same method for opening windows?

Hmm, didn't help.
Btw, I made a shell version of your sugarize C program. It's easier
to customize, feel free to use:
while [ -n "$2" ] ; do
case "$1" in
-b | --bundle-id) export SUGAR_BUNDLE_ID="$2" ;;
-a | --activity-id) export SUGAR_ACTIVITY_ID="$2" ;;
-o | --object-id) export SUGAR_OBJECT_ID="$2" ;;
-u | --uri) export SUGAR_URI="$2" ;;
*) echo unknown argument $1 $2 ;;
export NET_WM_NAME="X Logo"
