I know different systems may have different policies with respect to sudo-er lists, but would it be possible to check to see if you are in the sudo group on each system?
Code:
for h in $LIST_OF_HOSTS
do
printf "%s: %s\n" "${h}" "$(ssh ${uname}@{h} /usr/bin/groups)" 
done | grep sudo

This only works for systems that put users in the sudo, group and use the sudo group in the sudoers file, which will be the default, I imagine, but a decent, security-minded sysadmin may set up an alternative policy. Having said that, I once installed a SUSE (possibly openSUSE?) system where the user needed the root password to use sudo.
