Google appears to be experimenting with a new tool that could make it easier to swap data between various different Google products. It's called Cloudboard and is described on an internal feedback form from the company as a "server-side clipboard for Google Apps".

It also provides some examples of how Cloudboard would be used - copying a cell range from a spreadsheet to a word processor, creating an HTML table, copying multiple images from Picasa web albums, copying YouTube videos, copying events from Google calendar to Docs or GMail, pasting images into image search and copying maps into Google docs.

If this technology sees the light of day then it could set new standards for interoperability on the Web. For it to really catch on, however, it'd need to be opened up so that third parties can hook into it too. We wouldn't bet against Google doing such a thing.
