	An oddly common sentiment, but if the notation was peerTable[1, "sh-client"], would you feel so uncomfortable?

	Tables must be indexed, just like in a database.  You can (and many do) make your indexes as integers and make the group name a row object.  You'd then need to add a semantic restriction on name uniqueness if you still wanted such.

	You are programming the subagent to store data in a table.  SNMP operations will access that data.

	I don't know, but if I had to guess, I'd say that one handles a single index, and the other handles multiple indices.
