Maybe things will change now that processors are faster and memory's 
cheaper... but that's why they came up with drag 'promises', because 
it could take way too long to conjur up the data that your drag 
represents (imagine the Finder having to read a group of files into 
memory before the drag could really get started).  And the recipient 
may not want that data anyway.  So drags are designed to be 
lightweight.  But yeah, it should be easier than it is to turn those 
promises into data.
