Another example of this that bites me quite often is shopping.

I frequent several shops in a couple of towns. Some shops are in both towns, and some items can be bought in several shops. I can easily represent this as a context hierarchy:

@Town A (2 items)
- @Shop 1
-- buy Kettle
- @Shop 2
-- buy Shoes

@Town B (3 items)
- @Shop 1 (another branch)
-- buy Kettle
- @Shop 3
-- buy Shoes
- @Shop 4
-- buy Shelves

This demonstrates several conceptual problems discussed in the thread:
- Tasks can genuinely belong in multiple contexts (I can buy shoes in many shops).
- A context can have multiple places (Shops are not unique).

Clearly if this were allowed in OF as presented, there would be some confusion over task counts.
