Most NAS have CPUs that don't easily run the JVM. I wish AeroFS could run on my Synology NAS. That would be the killer feature for me.

I personally have the WD MyBook live (http://blog.marc-seeger.de/2011/03/20/the-western-digital-my...), it has an 800 MHz APM82181 (PPC Architecture) with 256 MB RAM, that should run most headless file sync stuff :)
