I do both

But like Stief it doesn't work very well to do both at the same time. I notice a great drop in how many uploads I get per session when acting as an UltraPeer

BTW I really wish that they would get that freeloaderfilter working. Then the people using Limewire can choose if Freeloaders are allowed RARELY (meaning people who share get priviledge in the queue). They get first the freeloader gets second
