I don't know if I am allowed to post link here so I will provide it through private messaging.
I am sitting here on an old wallet.dat with 50 BTC.
After reading all the comments in this thread I decided to set up a solution to share wallet hashes (not the wallet file).
This solution also splits the brute force tasks among a hashcat connected network of computers.
The only knowledge required is to be able to install python (as well as 2 extensions) to run the client.
It downloads by itself the necessary files (hashcat, the hash files and, if necessary the dictionary files) and share online the resources with the others.
For me the wallet is lost, so if peoples are interest to jump in, they only need to contact me and I'll configure them an account to share the resources.
If we are able to find the password, I will share the 50BTC to all involved participants.
Hey, it's definitely bad idea to share resources with someone you don't trust.
A better idea might be to share dictionaries and open private (known to specific people) hashcat brain server to the internet.
It will reject password candidates based on attack type and it's position. Of course one who attempt to guess a password should not send password hashes to the brain server, but only attack positions (--brain-client-features=2) otherwise network bandwidth and brain server resources will become a bottleneck.
I don't know if there are some kind of vulnerabilities in brain server, and if it's secure to open it to the internet, but it may be a solution to distributing the cracking power.
I'm interested in contributing in such process, so PMs are welcome by the way of making this happen we could learn to work with each other and build a trust.
