 I updated [wiki:UseCases The UseCases Page] to reflect that someone might
 want to run a managed Tahoe grid comprising one thousand nodes.  (If each
 node has a single 1 TB hard drive, that's a 1 PB grid.  Obviously there
 are lots of other options, such as each node having six 1 TB hard drives
 in a RAID-6 configuration, resulting in 4 usable TB per node or a 4 PB
 grid.)

 Anyway, we expect that the current Tahoe grid would have problems handling
 more simultaneously connected nodes.  One known problem is that pyOpenSSL
 uses almost 1 MB of RAM per SSL connection.  (See also #11.)

 This ticket can be closed when Tahoe is demonstrated to handle one
 thousand simultaneously connected nodes smoothly.
