Interactive CB field within a Joomla article

You've mentioned upcoming Joomla forms but I have a very simple use case, and I'm wondering if there's anyway I could get this to work today.

Is there any way to embed a CB custom field into an article that offered
1) a form for multi-select checkboxes (like in profile edit), and then submits the choices, or
2) just show the choices already selected.

What I'm trying to achieve is to let a group's members select which of 4 dates they prefer for an event.

There needs to be somewhere to save that data. The easiest way to do that is a form builder extension (something we're also planning as a future product!). If you're meaning you want them to edit a profile field within an article then that's certainly doable using CB Core Fields Ajax and a substitution.
