It was probably me, and it's variably true. There's definite breakage
and fragility. How much depends on what you do with it, and the phase of
the moon and the weather. I've even seen it work perfectly...twice.

But - as Mike-P said - I also thought that CARP was not dissimilar in
goals to ICP, although I can mentally expand the acronym and that makes
it sound different 'something-array-redundant-proxies' perhaps?

Whatever. The only thing that I've seen that uses CARP had a choice: ICP
or CARP, with pretty much the same config options for either. I suspect
CARP may be ICP+something more. ICP on steroids, if you will.
