How do you 'attach plenty of swap'?  Attaching an SATA drive is easy for 
me and I can format it anyway I need, but how do I point swap to it?

Thought so.  My C2 would be more than enough, except maybe the mail 
server.  But even it is not running all out.

I am waiting to see what the Allwinner A80 will be like!

Oh, no plan for sure!  Perhaps in late November based on Holidays and 
conferences.  I mean this month is kind of open, but more for some basic 
testing.  And some of my servers are still i686 so I have to wait on 
that too.

And I would rather spend the money replacing them with armv7 and save 
power than x86 and eat up more power!
