Subject: A naive question..

Why does PIM consult the Unicast routing table?
1)From what I understand this is used for mostly (S,G) entries in the
routing 
table and not for (*,G) entries.
2)I also understand that it is used for setting the iif for a source.
Why 
can't we set the iif as the interface on which we received this
join/prune.
3)And why doesn't DVMRP depend on the unicast routing table like pim
does?

Thanks in advance.
