After discussion, this idea has evolved away from fractional ownership of 
.eth and toward protection and development using a multi-sig.
Also @Premm.eth has proposed a subgroup for subdomains under the community working group, see:
One idea discussed is using .eth as a showcase and to create documentation for the ENSIP-10: Wildcard Resolution to resolve [yourENS]..eth for anyone that has their ENS primary record set, resulting in something of a “airdrop” of .eth subdomains to the ENS community. Hopefully I’m not misunderstanding Wildcard Resolution because I love the idea and would happily donate the domain to see that vision come to life for the benefit of the community and ENS ecosystem.
The next step is organizing people for the .eth multi-sig, please reach if you would be interested or if know someone that might have an interest.
