Your "regions" are not required to have a fixed size, you're not
required to use layout panels either. How about using SimplePanel
widgets inside a FlowPanel, without specifying explicit sizes? That
would work too.

In your case though, I'd probably go with either:
- Ashton's proposal
- make each "workspace" it's own GWT app (if they're sufficiently
different to deserve it)

- do not use activities (you can still use places if you like)
- use activities but make your own activity manager (or whatever) to
break the limitations and og beyond what's possible with the stock
implementations; maybe try to use a main activitymanager to switch
between workspaces, and then a set of activitymanager/mapper/regions
within each workspace.

There are many possibilities, and there are no one-size-fits-all.
