Ahead of tomorrows Google Developer Day (which I'm attending) Google have announced the arrival of Google Gears.
From their site:
" Google Gears (BETA) is an open source browser
extension that enables web applications to provide offline
functionality using following JavaScript APIs:"
Will be interesting to see what the reaction is to this at the Dev day tomorrow. More possibilities for RIA's it seems.
I wonder if it will play nicely with Silverlight...now that would be cool!
