Who knows what these agents will be used for? Maybe some large computational task where the agents move to hosts with spare processor capacity then move on again once the host become busy?

The concern I've always had about agents is that a denial
of service bug (or attack) is usually far more serious on
the server side than the client side. I expect that mobile
agents will only be practical in a very controlled environment,
with massive reliance on strict checking of trustedness
of the mobile code.
