I don't  see roundrobin as a solution. (details below)

CacheBoy would be the solution if:
- one or more for could join cacheboy
- if/when cacheboy is open source

Since the mirror do have delta's in the path Mirrorbrain would the
current solution.

It would not solve it.






so 3 out of 5 match, it does not look very promising when grow to more
mirrors. Thats why I like the CacheBoy solution.
