Hi,
maybe not of much help, but some general guidance...
- Core is crucial in whole system, cause MDs are all diskless and boot over network and mount disks over nfs.
- MDs can be used as Pluto MDs - if you boot them over network, or normal PCs as you have them now if you boot from local disk.
So actually trying Pluto would only imply to install whole system on Core, MDs can be tested without erasing their disks...
General guidance :
- Pluto Core can host : PVR (mythtv), video surveillance (motion), can also be MD (hybrid) core, etc...
Demands are approx sum of each individual feature...
Sorry cannot help much more - you'll know definite answer when you'll try it....
Are you familiar with Zoneminder ? I'm helping maintaining motion under Pluto, but am always curious about alternatives .....
Regards,
Rob.
