Mozilla Sunbird 0.5 Released
linux pickle writes "Mozilla has released version 0.5 of Sunbird, its calendar app. New features in this release include numerous stability and usage improvements, Google Calendar synchronization support, and much improved printing support. Check out the release notes or grab a copy."
Is a combined / integrated application that incorporated Firefox, Thunderbird and this Sunbird... that each part could be run separately if you wished.
It could save on the download because each part would share the UI code, networking code, etc, given that they're all built upon a custom platform layer, and each download replicates that.
Ah well, I'm sure it will never happen.
