Martin Porcheron is noting some potential Google products in their pipeline, and he's posting them on his blog.
Porcheron is a translator for the XX-Hacker language on Google, and based on his translations of Gmail, he's singled out a few snippets of text that imply what Google's currently working on. Porcheron points out a line indicating multiple user functionality for Google chat, which would be useful. Multi-user Google chat would move their communication tool into the realm of other instant messengers.
Also hinted is some Google AIM integration, and Google Spreadsheets and Gmail integration as well. Porcheron is kind enough to show screen shots of each line of translation, which indicate very little to the amount of speculation that Porcheron is getting at. But we've gotta start somewhere right?
