That sounds quite a good solution then.  Except, of course, that the
clipboard content size in the Message_DataSave may only be an estimate.  If
the clipboard owner has to do a lot of processing to work out the size, you
may find it always reports the size as some arbitrary number, like 2K.

Yes, but if you list 52 filetypes in your request the clipboard owner will
only give you the in one format it prefers out of those 52, a format which
you and other applications may not understand at all, and you will never know
it could also have given the data in an open standard format which you
happened to list further down the same filetype list.  I don't think this
could ever be made to work properly!
