I'm glad you asked :) Right now I'm offering a 200MB cache. The goal is to be able to 'burst' it. Hosting your own memcached is nice, and easy as you said, but then you are using your RAM and this can be a problem for some low cost linodes that are full of apps. If this trial works, I can relatively say that we won't be talking about 200MB, but GB of "burstable" cache. And you won't get it for free on Linode. Also, this is an experiment.
