As the title suggests, Google has rolled out a Flash based version of Google Talk called Gtalkr.
It includes a Yahoo Maps extension – as Google Maps is not Flash based – this is unfortunate because Yahoo Maps is US only 😦
Gtalkr also includes your Gmail account automatically (you log in using your Gmail credentials), so it looks like Google are trying to make this a home page for users.
Robin has correctly pointed out to me that the web-based Flash version of Google Talk is not a Google product – in a footnote on the base of the site it clearly says:

Time to get those eyes checked again Tom!
