Full Gigabit routing on Atom or Fusion board?
-
Check out the Pentium G840 2.8Ghz, it's a slightly slimmed down Core i3 for about half the price and is about 4x times faster on average than Atom/Zacate.
Mine is very quiet with the Intel stock heatsink and it runs cooler than my AMD Fusion (heatsink is obviously bigger/better though).
Here is a performance comparison:

Here are some performanceinfos for the d525

Atom CPU is not powerful enough for gigabit routing. Inter-LAN does not use pfsense so the internal LAN will be pure gigabit but data routed to and fro the WAN interface won't pass more than 250 Mbps or 300Mbps tops. It requires some good CPU power for heavy routing.
You need to get server class hardware or the cheaper route the latest i3/i5 CPUs that are powerful enough yet not as high on the power consumption like server class hardware.

Has anyone found a sandy bridge mini itx motherboard with two good nic's on it. Just searching myself now but as they are not as common harder to find.

Nopes, no sandy bridge or pre-sandy bridge mobo out there yet with dual port gigabit. I was looking for the same since as early as Jan '11. Also most of the single giga port mobos have a Realtek NIC. What you need to do is get a mobo with the common single NIC and attach a PCIe dual port Intel NIC. You can disable the onboard NIC through the BIOS.

Is the audio being piped to the internet, campus LAN or both?
I am inclined to believe that a fully managed switch with ACLs to act as a basic L2/ L3/ L4 firewall combined with an Atom pfSense (as NAT for internet traffic) might do the trick.

I expect the D525 would approach GBE wirespeed under some circumstances, depending on the NIC. I have a D510 with a pair of on-board Intel GBE that will do in the neighbourhood of 6-700 mbps throughput when testing with iperf. This is with net.inet.ip.fastforwarding enabled; results were lower without. The D510 is 1.6 GHz.
You may want to consider looking at the Sandy Bridge parts, which use no more power than an Atom under low load in my experience. If you throttle the CPU and/or the network links you may be able to operate it comfortably with all passive heat sinks.

Intel S1200KP.
I bought one ($163) and it works great with the G620.

This is indeed a perfect board for router, sadly it is never available in HK, even so will never at a reasonable price.

We ended up getting this: http://www.newegg.com/Product/Product.aspx?Item=N82E16816101364
We also planned on running a custom automation python script to run the radio station off air but alas it was fucking impossible to get sound working in PF sense, so PF sense is running in a virtualbox VM. Turns out we didn't end up needing the AOIP to route out over the router anyway (it's going out over AES to worldcom IP codec) so WAN speed is fine so long as it can hit a couple hundred MB/sec.
I also got one at my job to run BGP for our 2 fiber links but my boss didn't want to use pf sense since we already have a checkpoint firewall with 10 or 12 remote offices licensed.
