It does look like we will be going with Dojo. I've used all the
major JS frameworks in projects, from YUI to EXT to jQuery to Dojo to
Mochikit to Scriptaculous, you name it. It used to be that Dojo
wasn't an option because it was rather large and slow, but times are
a-changing. The new speed, coupled with the existing widgets and
themes and accessibility, makes it very compatible with the goals for
Tortuga. Also this is going to be the default for
TurboGears/ToscaWidgets, so that's another benefit.
I just released the 0.1 final version of Checkpoint, and now I'm
getting ready to release the next developer's preview - which will
contain just about all of the back-end code except for a finalized
rendering system (the current rendering system is just a plaything).
Look for an email tomorrow!
