Hosted Memcache??

Gear6 is creating a hosted memcache layer, http://www.gear6.com/web-cache/overview/scale-your-web-site-applications..., that may help bring memcache to sites that don't want to set up their own memcache servers. They are hoping that be a capacity player for large companies that already have memcache server farms, as well as opening up this technology to new, mid-tier websites. I am hoping this and other like services will quickly be assimilated into the network of Drupal integration modules for performance.

And by the way, the corporate and Gear6 Community sites were built with Drupal.
