[flexcoders] Flex (w/ LCDS or BlazeDS) Hosting options...

Where do you host your Flex app that requires LiveCycle DS or Blaze DS? When a hosting company claims they support CF8, does it usually include the embed LCDS? Is dedicated server the only way to go? Is RMTP channel practical for flex on Internet? or just for Intranet? Thank you.
