Hey Vin,

Well, there are "transient pages," which you should not have to bmk...
And pages that should be bmkable (or refreshable, for that matter).

The issue has been discussed countless times already, although not quite
on this list, as it is a non-Spinoffs-specific thing.

Pulled from my archives, here are a few links that might be of interest
to you, pertaining to AJAX accessibility and ergonomy in general:

  http://particletree.com/features/degradable-ajax-form-validation/
  http://www.baekdal.com/articles/usability/usable-XMLHttpRequest/

The way I see it, the "best" (although a bit unsatisfactory) way is to
provide clear, standing-out "Refresh" links (e.g. eBay on bid pads) and
"Bookmark this!" links (e.g. Google Maps on specific views) ; so your
server side has a URL (de)serialization mechanism in place that can
encode a transient state and use the resulting URL to restore it later.

'HTH
