eg. if someone is at home and answers work emails even tho they normally at work in the day thats home working, and any isp coming down on that would be seen as very harsh.
In practice you can use a home package but you not going to get a business SLA, so faults and the like will be treated with low priority. The isp will be ok with it as long as you dont start telling them its business critical when it goes down.
