The new version of Google Talk supports file transfers and voicemail messages to both GT users and non-users (it sends the latter an email with the voicemail as an attachment). They’re rolling it out slowly, but if you want to try it out now there’s a direct link. The only available version is US English, so if you’re anal bothered about seeing the word ‘color’ or whatever within the interface you may want to give it a miss.

File transfer is a feature I’ve needed in Google Talk from time-to-time, so this is a good addition imho. The only outstanding feature I’m bothered about is multiple-person chat windows; then it’ll be a worthy MSN replacement. Via Digg.
