round-robin aliases

[Ryan D <netfilter@mandrake.us>]

Ive been trying to find a way to do this... I have eth0 on the
192.168.2.0/24 network (eth0 has ip 192.168.2.10). I also have 5 aliases
on the same network with these ips:

eth0:1 192.168.2.11
eth0:2 192.168.2.12
eth0:3 192.168.2.13
eth0:4 192.168.2.14


Id like to round-robin the source ip on a per connection basis, meaning,
if I ssh to 192.168.2.100 it may come from eth0:1, if I then ssh to
192.168.2.110 it will come from eth0:2, etc.  So the destination ssh
machines will see different source IPs.

Is this possible with netfilter/iproute2?  The only potential problem I
see is with the arp table, but I also dont understand this stuff as well
as I would like.
