BreakingPoint adds Windows Live Messenger support

It's interesting that a lot of the industry is focusing on chat and messenger protocols, along with things like P2P and file sharing. BreakingPoint announced recently that they added support for Windows Live Messenger - their list of supported protocols in this area now includes AIM, IRC, Jabber, Windows Live and Yahoo!. Most of this seems to be focused on service provider testing, but I'm still really curious because there aren't thousands of SP's out there that would buy features like this, at least I don't think there are..... Is it really that important to have these protocols for the Enterprise or other markets? Or is there really a huge SP market, and I'm just out of touch? At least in my day to day, I don't test with these protocols, and probably would only ever use them to show traffic mixes that are more realistic, but it wouldn't matter if the protocols were exactly specific to the provider (AIM, Yahoo!, etc.). Something generic would be fine with me. Full press release can be found here.
