We have encountered cases where a vendor TFTP implementation + latency from the ROMMON can take a few hours to load 
images.  I'm for ditching TFTP and replacing it with HTTP.  This forces them to put in a TCP stack, and hopefully 
something that can window-scale and deal with the latency vs 'wait for block', ok, req next block..

The testers involved in their labs are never loading an image from 1600km away so don't get to enjoy this 'fun'.
