It's easy enough to enable with a GConf key

gconftool-2 --direct
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t bool
/desktop/sugar/show_logout true >/dev/null

Yes, for the OLPC deployment all the Activities get installed in the
local user directory. For SoaS and Fedora in general where we package
Activities as rpms they get installed in /usr/share/sugar/activities/

I've heard of a couple of places using sugar multiuser on desktops and
even one (or maybe more) using it with thin client/remote X setups
with multiuser without issues so it's certainly usable in this manner.

IMO the gdm login is the only really workable solution. Things like SD
cards or USB sticks are likely to get lost by youngsters.
