web servers: not much of a problem.
caches: doesn't look so good. squid can't store chunks of a file. So
the options you have are:
(a) configure squid to pass through range requests to the original
server. Which kills any caching.
(b) configure squid to fetch the whole file no matter what.
Subsequent requests (including range requests) will be served
from cache then, but zchunked rpms wouldn't save any bandwidth
then.
