Write your reply.

assistant: The tone of this thread is harsher than I really like, but the subject is
important, if only to prevent future GOSIPs. (What a waste!)
I am bemused by your attitude here, if one devises a workable protocol and
one enters it into the public domain, does one not STILL have pride in it?
As for retaining rights to the name, one needs SOME way of contolling cheap
ripoffs, how many 'Hayes compatable' modems, actually uses the same commands
as Hayes?  Computers which claim to support NFS, do in fact interact with
other vendor's NFS implementations.  Sun is working now to make sure that if
it says 'Java' it IS Java, and not some hack, that does not mean they are
limiting the use of true implementations.
Sun documents their protocols publicly, does not charge other companies for
use of Sun protocols, and tests other vendor's implementaions to insure
interoperability, this is hardly proprietary.  If open standards of the kind
you seem to approve were viable, we would all be using ISO's OSI networking,
but in fact, committee's invent little that is innovative, and often have
trouble just recognizing what works. (SNMPv2, anyone?)  I am a fan of
openness, but fail to see 'free, but do it our way' as closed.
Nor am I, but it does mot matter if I run RIP or OSPF, the PC stack is still
too dumb to correctly interpet a reply from a port it did not send to, so we
must give them hints, or forgo multi-port servers and send all traffic
through routers.
As for the XTerms, the first T in TFTPBoot does not stand for 'Trivial' for
no reason, it is too dumb to correctly interpet a reply from a port other
than the one it queried.  We must explictly specify the IP address of the
closest port, only after the boot image is loaded does it learn to use NIS.
