Although does that mean the full extend of URI scope. Which includes ftp, mailto, nntp, and I am sure I am missing a few others that are resolvable through URI. and does number 2 apply to those URIs??

Since HTTP doesn't maintain a connection if communications appears to drop out. A RPC that takes more time than the communication timer is allowed for and the connection is dropped. I suppose there are ways around it. (write the client to periodically check for new info) I appears to me that a RPC standard that relys on the disconnected standard of HTTP would have some limitations. (a certain limit in processing time of a procedure for instance) Excuse me if these seem a little daft, but just my observations.
