Ok, as I will have few hours of free time I will come to mentioned IRC channel. Right now we have our own svn tree of linuxmce code which was splitted from official sources of version 710 with several patches from other svn trees we found on that time (official code has a few bugs, with fixes found in svn trees right after release date). The primary concern for me is not the pataches against code but rather database synchronization which required for example for new device.
As for server hardware this is Q6600 CPU, 4 GB RAM (actually ram is not an issue at all), 150 GB 10K RPM WD Raptor for system and orbiter filesystems, 2x1TB 7.2K RPM joined as 1 TB RAID 1 for video. Server has also additional COM ports for EIB and our own controllers and Digium telephony adapter.
For video capture we initially use 2xPCI 4XBT878 no name adapters. But later found that with full PAL size and 25 FPS PCI can handle not more than 4xBT878 chips in theory because of PCI throughput limitation. In practice even with just four cams (chips) and the minimal possible color resolution (YUV420) on different mainboards the system might work or not work as the PCI usage was on edge. So this adapters was replaced to PCI-E version PV-981 (http://store.bluecherry.net/4_port_video_capture_card_120FPS_Real_time_p/pv-981.htm
) and they work pretty fine and stable. Up to this date server work about four months without rebooting.
