My own private home build ser= ver is (essentially) a cluster of two AMD8160 8-core 32 GB servers connecte= d with 40 Gb/s Infiniband and a 6-way RAID5 storage array on one of them th= at gives quite nice read performance.  I'm not worried about how long = it takes to do a build...

= =0A

Anyway - the recipe doesn't have to be = perfected for me to use it - and I suspect it's similar to OpenWRT's build,= so maybe pointing me to the best help for that and what the differences ar= e would be great.

I promise I will write the "port" experience up= and post it on the Wiki, in case others want to port cerowrt to other "Ope= nWRT platforms" of sufficient capabilities.
