You never know when any company is going to die, change directions, or be 
acquired by Oracle, but VMware has a fairly long history of providing 
increasingly better free offerings (better in that respect than RedHat...) so I 
would downplay the risk of it going away.  The main issue with using ESXi is 
just that you need a windows box to run the client when you want to change 
configurations or access the guest consoles.  And with the free version you have 
to use the converter program to copy images in or out (but the converter is very 
well done).
