LW default is 3. Bearshare is 2. Now you probably talk about Pro which is 5, but they are less than 10% of Limewires and help to pay the programmers for improving the code YOU use.
Why are you avoiding talking about Cabos, the changes aren't the same as Acqlite?

PS: if you could send me the diff here or by PM, that would be great
