I've seen a few questions here on S.O where people recommend "checking out Qizmt", but has anyone actually deployed a Qizmt instance and used it? Do you have any reviews/tips/tricks/gotchas? How does it compare to other distributed computing implementations? Ease-of-use, performance, etc. are all valid review points. I assume that if MySpace invested in the development, and is using it in production, it can't be THAT bad, but any thoughts are more than welcome.
I can't seem to find any actual reviews on Google, so if someone is a better query-ninja, links to reviews would be helpful too.
