We have encountered cases where a vendor TFTP implementation + latency

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'.

Re: other comments:

        - tftp: I've run into enough problems with stupid tftp incompatibilities
that I'd be really happy never having to use it again in my life.

        - netflow: seriously, this is not an appropriate sort of port of exporting
netflow.  this is a "your RP is toast" recovery mechanism, at which point
netflow is probably long gone.

        - rs232: please no.  it's 2013.  I don't want or need a protocol which
was designed for access speeds appropriate to the 1980s.

        - USB: no.  can you route USB?  No. DNW.

        - original list: sounds great, except that I want ipv4 and ipv6 given
equal priority for mgmt access.
