Nice dual gig nic card in 1 slot.  Will this work in LMCE?

Is it based on desktop or server?

I am looking at implementing a solution with ClarkConnect as a residential gateway server and LinuxMCE as a media center/ server and home automation controller.

I suggest that since LinuceMCE runs on Kubuntu, that you implement the following functionality in it to make it the ultimate residential server:

 Provides core server applications
- web, VPN, backup, file and print services... 
 Protects network and data
- antivirus, antispam, firewall, intrusion prevention... 
 Enforces Internet usage policies
- content filter, peer-to-peer filter, bandwidth manager... 
 Simplifies management and monitoring
- system monitoring, software updates, ... 

Look at monowall, Pfsense, ebox, OpenVPN, etc.  All open source packages.

This would truly be a killer server.
