Push and Pull subscription?

As I understand replication in Sql2K the only difference in push or pull subscriptions is where the agent runs. If I wanted changes in the publisher to be sent to the subscribers immediately after the change then I thought push would be better. But, if I am equally interested in changes made at the subscriber then what should I use? Or does the agent monitor both the publisher and subscriber at the same time?

Thanks for your help

Graham, assuming you're talking about merge replication, changes will be propagated up/down whenever the agent runs. If you run the agent in continuous mode, then the changes should be sent within the polling period of the agent. If you run the agent in a scheduled mode, or on demand, then the changes will be sent when the agent runs.
