Are the hardware requirements really so modest? A few weeks ago I tried experimenting by importing just Europe and it took a week (on my machine which has 2GB memory), so I gave up on the idea of having my own whole planet database. Then I had major trouble with the database size growing, and never really got the 'trimming extra nodes outside of the bounding box' trick working - that seemed to take so long that I gave up on it. Maybe you need to do that after each import, rather than prune it once a week....
If people are managing to maintain their own database on modest hardware, I would be interested to know what hardware and software configuration they use, because I am thinking of investing in a virtual server to do it, but want to go for minumum specification to save on the cost.
