I am thinking it is about time to move my wife's website up to a virtual
server of some sort (currently on a shared server on bluehost).  I was
looking at slicehost and a couple other hosts but I am not sure of the size
host I should get (or even the best company to go with).  The website runs
OSCommerce, Wordpress, Zenphoto, IMAP, Roundcube (or other webmail)  and one
or two various web apps for testing.  She also hosts short term, low traffic
websites for misc uses.

Any ideas on proper sizing?
