After having actually dealt with a station wagon (actually a van) full 
of 9 tracks (400-9 tracks, 100-3590s), I thought that I would chime in 
and second some of the responses.

Until there is a general access to Lambda speed connections, the 
applicability of cloud computing for jobs requiring intercommunication 
will be limited. Specific examples of the limitations would include MD 
codes and Quantum codes.  There are issues, even with sequencing data. 
Our sequencers are generating 90 GB every three days. Moving that 
information to a cloud for analysis would be painful.
