Advanced Queue Limit and Configuration Best Practices

I'm curious why there is a 1024 queue ID limit with advanced queue.  I'm also curious how if queue IDs are set to service lower (numerically) when targeting a specified source/destination, how do you configure a separate rule that limits something like video streaming to that same IP/subnet AND also uses the other filters that are higher numerically that may shape a specified ceiling.

IE:

Leaf ID - 100 - Customer 100, bandwidth - 64kbits, ceiling 10Mbps
Leaf ID - 101 - Customer 100 streaming, match protocol 'streaming', bandwidth - 64kbits, ceiling 5Mbps
