I'm a PyQt newbie so maybe there's an easier way, but I wrote my own.  I 
saved out various view attributes, swapped in a new model, and then set the 
view to those saved-out variables.  It works well and to the end user the 
table just updates without losing any context.  It's a little annoying to 
code, but I was able to save out and set selections, sort order, vertical 
positions, column size, and column positions.

The problem with selections is when a new model has a different number or 
order of elements.  For example, if the first row is selected in your 
current model, then you can easily set the first row as selected when you 
reload the model.  However, the first row in the new model may be a 
completely different element.  I worked around this by designating a unique 
key for each row.  So instead of recording which rows are selected, I 
recorded which keys were selected.  Then I had to search through the new 
model and find those keys and select them in the selection model.
