I am creating a "dashboard for the netInch type of application, much like iGoogle or Netvibes. Clearly, this involves plenty of HTTP demands to become produced from the server - different services need to be questioned in a nutshell times to update the information for those customers.

Since we are coming closer to the stage of launch, I am considering webhosting. We do not need much diskspace, memory or CPU energy. The traffic shouldn't be excessive under extreme usage because the site is very lightweight, and a lot of the API demands will remain clearly below 1KB.

So I am curious about what we should really do need. What needs must i have when selecting a webhoster?

Obviously any concrete recommendations for webhosters are welcome, too.
