The idea is great!

If users feel that Morpheus Ultrapeers give them less results, they can now choose not to connect to Morpheus at all.

The other options, to respond only to LimeWire queries has been added, since I felt that it can be benificial for people sharing thousands of files like me, who are flooded with search request which causes an constant outgoing traffic of 6-7K/s just for the message traffic as a leaf node. With the ALLOW_ONLY_LIMEWIRE_UPLOADS option set, it is reduced to 1k/s, which is a figure I can live with.

And as for the network being "split up", - I can live with that too, as can many others who prefer a well behaved network over the ability to connect to Morpheus ultrapeers.
