Haha, yeah, I agree. The data file is awkward, especially since the code does not search the path, so you need to cd first to be in the directory with the file before you run it. Not sure how it would work with the mac app packaging either. I am hoping it is a temporary kludge and not a permanent fixture.
Yes, it's a kludge, but we incurred some technical debt when we forked rather than restarted at 1566, so this file is going to be required going forward, it's just a question of finding the most elegant way of including it. Open to suggestions on that. Also the trustedhashlookup.txt file is increasingly going to be required for new client to get synced in a reasonable time, so I think we'll end up including the two files in the same way.
Also, will get the 21st Century peer node included in Github in the next update.
