No - I use different GUIDs for different versions. It is specified in the
manifest.tmpl file.
But I also have more than one stick for testing the U3 support - lots of
launchpads!

I have been doing it "by hand" and checking a change in at each version
change so far.
But it is probably time for an automatic approach. I'll see what's available
for creating name-based GUIDs - or write something. Does Wireshark already
have an allocated GUID (which I could re-use for the namespace)?

A tooltip comes up when I hover over the application name in the launchpad
window.
I'm running 1.2.0.5 on a Sandisk U3 device. The launchpads are slightly
different between vendors as well which doesn't help - see
http://wiki.wireshark.org/U3Packaging for what the Sandisk launchpad looks
like.

It is worthwhile doing - you can do it from the Launchpad (or at least you
can on my Sandisk launchpad!).

Will rebuild and test.

Will do.

That will simplify the U3 interface too as it won't have to ask on the first

start of the application. 
There will have to be a little bit of U3-specific code - i.e. mark the
WinPcap as being installed by the U3 device, so it can uninstalled when the
U3 device is removed - but that is fairly trivial.
