I haven't finished reading through all of the details in the document you 
created in the wiki, but it seems to be a design document for a new/different 
cloud system.  I didn't see anything explaining how it relates to VCL in its 
current form or a roadmap providing a migration path from the current form to 
what you've designed.

That aside, can you explain further why you are proposing this?  I think I'm 
seeing a bit of a cart before the horse issue here where you've designed out 
something new before there's been any discussion on this list about whether 
or not large parts of VCL should be redesigned.

After explaining your reasoning further, I think it would be a good idea for 
us (the community) to have a discussion on this list about any areas of VCL 
that are needing to be redesigned.
