From the roll-your-own side, have you looked at an alternative Nagios event broker called livestatus? It's written by Matthias Kettner as part of his client-centric mk-check Nagios plugin suite.
Regarding this in reflection of this email livestatus won't make that much sense. Earth is asking Space for some livedata, Space answers?

Correct. We are looking to use Nagios to monitor various parameters on our network, then store them in postgresql, which we will then synch to the ground and distribute as a quasi realtime telemetry system.
But anyhow... Peter C. Lai wrote:
At the moment it only brokers live data (hence livestatus), but it is intended to replace NDO as the general event broker. You can read from the socket and do whatever you want with the data...
Depends on the use case. If you want something that continuously spits out data, and stores that elsewhere, without the need of initiating the output, you'd better use IDO (compared to NDO it has ~35% performance increase). If you prefer to demand data by a client application (like a web ui e.g.), livestatus fits best and performs better. You might use livestatus as a data poller too, but that implies bidirectional communication and can lead into performance issues and problems.
Regarding this situation, and basically the amount of data being generated and reworked, I would consider that NASA chose Postgresql wisely as RDBMS - maybe even the monitoring backend depends on unified APIs for alerting and reporting and so on. It would be interesting how many hosts/services will be monitored and how this relates to the check rates.
