either ssh tunnels, or for more flexiblity, you might look into OpenVPN 
which supports routed or bridged virtual networks over an SSL socket.

with a 'handful', you'll need to determine what topology you want, most 
VPNs are built in a 'star' fashion where 1 central server acts as the 
VPN router and all other systems connect to it.   you COULD do a fully 
meshed topology, this would just require createing more tunnels and 
routes (for instance, with 6 hosts, a star would require 5 tunnels, 
while fully meshed would be 15 tunnels.
