Here are some initial thoughts...
*Is your son teething?
*When he wakes up is he rewarded (kissing, cuddling, lots of attention, tv, snacks, etc.)for waking up?
*Could it be separation anxiety?
*Does he have a scheduled bedtime and structured routine (this is very important that he does) every night?
I teach a newborn care class and one thing I tell parents is "Don't be your child's pillow." That means, let the child learn how to put him/herself to sleeep and BACK to sleep as we all wake up several times throughout every night.
I know your concerns for your husband's need for sleep are right on...however, sometimes parents loose sleep initally for the benefit of a child who sleeps better in the long run.
Ferber has recently modified his sleep advice to be less harsh. Also, Dr. Sears has modified his sleep advice to be less "child-centered" as he recognizes the need for parents to get sleep too.
10 months is too young to "reason" with him so the method you use will have to be simple and immediate. For example, there may be a certain cd that is played at bedtime every night. That becomes an audio "clue" that it's bedtime.
Bottom line, do what's comfortable for you and remember: Your son came into YOUR life, not the other way around.
Good luck!
