The LDM can probably run "in the cloud" in some sense. The problem comes in 
paying for networking. Mike Schmidt looked into this a while back. Cloud 
providers can provide very reasonable rates for disk storage and CPU time 
because the buy and own the hardware. Because they don't own the networks, 
however, a cloud-user must pay the third-party ISP for bandwidth -- and they 
appear to be unwilling to lower prices. For something like the LDM, paying for 
bandwidth becomes the overriding cost.
