The URLstatus function looks nice, but seems focused on receiving data,
rather than providing information about an upload process. Will it return
any information relating to an upload? Will at least the "contacted" result
return true if a connection is made for upload? Will "error" result if the
server is not found?

I'm not too clear on this - does an upload which is finished provide any
indication of that status? If the socket does not automatically close when
an upload is done, and URLstatus does not provide an "upload process done",
how would one monitor status of a queued series of uploads? I would ideally
like to restrict the queue to four simultaneous connections, and as
processes finish allow more queued upload functions to take place.

Thanks for any advise.
