well, the IDS would be primarily to protect the rest of the internet by noticing when your box becomes a zombie (and decrease costs associated with handling abuse.)
Unless you are one of those people who expects me to leave your box online after it has become compromised and is spewing abuse, the ids, assuming I use it how I say I'm using it to just detect compromised hosts, and assuming I'm careful about false positives, won't hurt you.
Mucking with the traffic is /much/ more difficult to do without damaging the service. However, there are many cases where if you muck with the traffic you can allow high latency high bandwidth bulk transfers without messing up your low-latency traffic as much as it would otherwise... e.g. it's possible, with traffic shaping to maintain better customer experiences while overselling your pipe.
this positive is realized by the customer through lower prices in markets with competition. obviously, the home broadband market is not one of those markets, so I don't know how much difference it'd make there.
If you notice, I'm a provider in the server space, where there is a lot of competition.
