Anyone know how much disk space and ram a standard ubuntu install on mongo needs? trying to map out my VPS needs ...

There are no minimum requirements as such, but I wouldn't recomend running Mongo on the same box as your webserver. <blockquote> MongoDB automatically uses all free memory on the machine as its cache (http://docs.mongodb.org/manual/faq/fundamentals/#does-mongodb-require-a-lot-of-ram) </blockquote> This, along with the reasons mentioned in this answer (albeit for RDBMS) makes running mongodb on a separate box (even a small one) a much better idea.
