In article <2994@redstar.cs.qmw.ac.uk> timk@cs.qmw.ac.uk (Tim Kindberg) writes: I know about the common case of transmitting sending port *send* rights. I am interested in sending port *receive* rights. A server can send port receive rights in a message in order, for example, to transfer its client(s) to another, less loaded server. Hmm...I can't think of any case aside from task initialization where the GNU multiserver design sends receive rights. Some may arise; there are places where I think I'll do it, but it's a kind of esoteric occurrence. I suspect that the rarity of sending receive rights would justify a netmsgserver which was speedy, and sending a receive right was potentially expensive. -mib
