Yes.

No - you should be thinking in terms of registering a single row of the table.
The OID range is used to indicate the list of column objects to register,
all sharing the same index value.

Set up an OID array containing the full numeric OID - *including*
index subidentifier(s) - of the first column in this particular row.
Then use 'range_subid' to indicate which subidentifier identifies the
MIB column object, and 'range_ubound' to indicate the last valid
column.

Repeat this for each row in turn - using the index returned from
'register_int_index'

What's the OID that you pass to this routine?
*That* must be the same for each subagent (typically the OID of the
table itself) - so that they know they're working with the same set of
indexes.
  The OID passed to the 'register_mib' (or similar) call will be
different each time, since this refers to a particular row.   But the
shared index allocation needs a common OID to register indexes
against.
