Lupins are a great, high protein feed. They generally aren't likely to make horses too fizzy either.
I feed my horses flaked lupins and they have made a big difference to their weight and overall condition. I soak mine for about 10 minutes prior to feeding (mostly just because they get Hygain Micrbeet too and that needs to be soaked for 10 minutes). You are right in that cracked/flaked/crushed lupins are safe to feed dry. Although, there has been stories of some horses having an issue with choke if they are fed dry. Whole lupins must ALWAYS be soaked before feeding, generally I believe 24 hours is the rule.
How much to feed is really dependant on what else you are feeding. My guys get between 250-600gm per day (easy keepers get less than the hard keepers), however they are also being fed an array of other things too.
