Sounds to me like you're taking snapshots of the data, and
displaying them independently of each other. Is that correct? If so,
does the data need to be read/write, or is it for display only?

Probably you'll have to add some logic to your bizobj class to
handle these 'snapshots'. There is already a similar facility for
this in the _CurrentCursor property, which is designed to handle
multiple sets of child records, and this cursor is based on the key
value of the parent. Perhaps you could create a key value for each of
your viewer panels, update bizobj._CurrentCursor when the active
panel changes. Take a look at that property and let me know if it
makes any sense to you.
Managing the 'active' viewer will be the trickiest part of the whole
thing, especially if you are planning on being able to edit and save
changes to the data.
