Yes, and that is really what they will use even if mIRC adds the feature. Teamspeak and Ventrillo (or however you spell that) are very popular just because it lets you coordinate attacks and such very quickly and easily without typing while playing games. They aren't really used for general communication because people don't really want to do that. Even on IM, people generally don't want to do voice chat. And with more and more phone companies (at least in the US) allowing unlimited long distance, you might as well use a real phone to talk to someone. Obviously, from other countries, you may want to stick to communicating over the internet, but most people who want to voice chat that way are families that have members located in other countries and not just people who've met online.
