Anyone in this community can get together with others and start there own XNN EOS mainnet.

Snapshot tool could be tweaked to snapshot ETH network for XNN ERC20 token instead of EOS ERC20 tokens: https://github.com/EOS-Mainnet/genesis . I would suggest that the community considers excluding distribution to whales of unknown origin or allow the community to vote on the distribution of these holdings. Or possibly have the community fund an account/alias creation dapp funded by those holds to pay the cost of creating aliases for new community members.

Then the community needs to have members that want to be block producers work on a mainnet. Probably better off waiting for the current EOS BP candidates to flesh out the process, currently on  going, and work through any additional bugs of issues.

If you are interested in being a XNN BP I would suggest starting with https://github.com/EOS-Mainnet/patroneos . patroneos was provided by block.one and is an effective way to protect your exposed http/https eos api endpoints.

Eos developer portal using docker will have any developer up and running on the platform in under 30 minutes: https://developers.eos.io/
