I think your trivialising your solution way too much, and the issues in
general. If your proposal is so easy and so risk free don't you think that
most of the Live Media projects would have gone this route. Also who is
going to do all the QA and testing on this on dozens of various sticks and
various other media to see what the issues are with different formats, USB
keys, memory cards and what ever other media or formats that are used.

The advantages of the current way we do things are as follows:
- Works, tried and tested in Fedora across a lot of releases, 4 platforms,
and 1000s of media types
- Can be installed to a proper install as your proposing using liveinst
(this just needs to be documented as a procedure).
- Can be used on CDs as well if desired (your solution won't work here)
- Can be easily booted on all Virtualisation solutions
(KVM/Zen/VMWare/Virtualbox/Fusion/Hyper-V etc) with no changes as they all
support booting off a CD iso image (your proposal would need the VM drivers
for at least storage to work properly for all of them)
- The QA that happens as part of all the upstream Fedora releases for Live

The disadvantages of your proposal (as I see it) are:
- Some one needs to do the coding to produce the images
- No upstream QA
- Doesn't work in all environments that we currently support so we'd need to
have Yet Another Image
- No wide spread testing
- Lots of corner cases that would need to be documented or developed around

I personally believe that the best way to get both capabilities would be to
continue to ship the Live Media as we do now and document how to use
liveinst to have a 'proper install' onto a USB key that is bootable. This is
supported upstream and is hence very well tested and is known to work well.
It shouldn't be too hard to even add an Activity icon or Control Panel icon
to start the liveinst off (does Sugar support something the equivalent of a
.desktop file) like Fedora puts a "Install to your harddisk" icon on their
Live Media desktops.
