If I were you, I'd buy a cheap switch which would save you some trouble. 
However, the ip addresses don't seem correct to me. you'll have to put 
them on seperate netmasks. the easy way to do that would leave ae1 how 
it is, and change ae2 to 10.0.0.1 netmask 255.255.255.0 and set windows 
to 10.0.0.2 netmask 255.255.255.0  if packetforwarding is enabled,(and 
default routes, for that matter) pinging 10.0.0.2 from 192,168.0.2 
(windows -> mac os x) should work just fine.

I think the problem lies in that those networks you set up overlap, such 
things are not allowed. Someone please correct me if i'm wrong.

I dont know anything about all memory not seen.
