Got it to work after all using the method of storing the new options in $form_state[storage] and then, if it isset during the subsequent hook, force-feeding the field with the values from the form state.
Thanks very much Dave and Jamie!!

Actually you never really know what is going to happen in validation. So many modules can do funky things. A lot of times the multi-step type forms handle the rebuild through a submit callback.
There's another option here as well, depending upon the criteria that has to be met, and that is using the #states system. You can see an example here:

Actually you should be able to alter the form in the validation function yes? Just change the function signature to pass $form by reference and make the changes to the form that you need rather than going through the later hook?

Ok, I've tried that. The last thing I do in hook_node_validate is $form_state['rebuild'] = true; What I notice is that hook_form_node_form_alter does not fire between then and the form being redisplayed, so my pulling the options from $form_state['storage'] never happens.

The checkboxes have to be added in the form creation stage, so in either hook_form or hook_form_alter. Then in the hook_validate, set a variable on $form_state['storage'] and set $form_state['rebuild'] = TRUE; and check in your hook_form or hook_form_alter for your $form_state['storage'] setting, and if set then add your checkboxes.
I suggest looking at the form_example_wizard in the examples module, as that's basically what you are after, even though it's not a typical multi-step wizard you are after, the logic is still the same.

One thing that is either part of the issue, or a separate issue that impacts this, is that the checkboxes field is added via hook_form_alter. I notice that although the field appears in $form_state[values] it does not appear in $form_state[field], so I'm wondering where $form_state gets the information for the field when rebuilding the form.

I have a node form that contains a checkboxes field with options NULL at the time the form is displayed.
During node_validate, if certain criteria is met, an array of options (checkboxes) is created, and the form needs to be redisplayed with the checkboxes as part of it.
I've tried setting #options = the new array in the $form, in $form_state[original_form], etc all to no avail. The field doesn't change.
I also set one checkbox in the field at the start, so that I could find it in the $form and $form_state structures, changed where I found it to the new options array, and again, no change. I am setting $form_state[rebuild] to true, and even tried explicitly calling for the form to be rebuilt.
