I believe there're plenty bitcoind instances running, = but they don't have configured port forwarding properly.There's uPN= P support in bitcoind, but it works only on simple setups.

The list has open membership, there is no particular qualification or=
background required to post here. Optimal use of an information source
requires critical reading and understanding the limitations of the
medium. Counting comments is usually not a great way to assess
technical considerations on an open public forum. =A0Doubly so because
those comments were not actually talking about the same thing I am
talking about.

Existing implementations are inefficient in many known ways (and, no
doubt, some unknown ones). This list is about developing protocol and
implementations including improving their efficiency. =A0When talking
about incentives the costs you need to consider are the costs of the
best realistic option. =A0As far as I know there is no doubt from anyone technically experienced that under the current network rules full
nodes can be operated with vastly less resources than current
implementations use, it's just a question of the relatively modest
implementation improvements.

When you argue that Bitcoin doesn't have the right incentives (and
thus something??) I retort that the actual resource _requirements_ are
for the protocol very low. I gave specific example numbers to enable
correction or clarification if I've said something wrong or
controversial. Pointing out that existing implementations are not that
currently as efficient as the underlying requirements and that some
large number of users do not like the efficiency of existing
implementations doesn't tell me anything I disagree with or didn't<= br> already know. Whats being discussed around here contributes to
prioritizing improvements over the existing implementations.

I hope this clarifies something.
