- 'Voting' should then also be possible by running a completely different client, implemented by other developers.
This is already possible.
Sounds like a great project. Are you volunteering?
- The default client should not contain limits that prevent running other versions / clients. If the default client won't distribute transactions with a fee less than 0.01, it's going to be very hard to run a client that allows a minimum fee of 0.001.
Shockingly... people are already doing that which you describe as "very hard" simply by upgrading.
Re-read the part of my post about people voting with their downloads.
Then re-read the other post about transaction fees already changing.
Then read the thread on transaction fees changing to 0.0005.
And maybe study how mining works, too.
Same with the version number misery...
No idea what you're talking about here.
