What about a probe that can be launched in a system and the user can then monitor instantaneously, the number ships that are in the system via the map. This would allow remote monitoring of one or more systems for hostile/friendly fleets. The probes could be given a maximum duration and the pilots skill would decide how many he could have active at any one time. The map functionality would be similar to how it was before the updates, but would only report on systems with an active probe.
