This is exactly what I need. Essentially, some sort of selection  
representation and arbitrary key/value pairs. The values would need to be  
stored somewhere. Any ideas where/how to store them? Perhaps a database?

Is it overwhelming because of the time it takes to render text?

Some sort of table view would be great. Each row would contain the  
attributes about whatever data was previously selected.
How can this be done with a python filter now?
