What I was thinking was that if we can identify the owner of the pool, we could
use this information in some situations. For example, when performing search
with urn, how we can be sure, which one of the returned blocks is the correct
one (e.g. 'NYT front page'). If we know, to which pool a specific block belongs
to, we can make decisions from it (e.g. NYT is the owner of Storm pool,
identified by a key) and select the 'non-false/correct' block from the search
results' list.
