For a look at an open source system to incrementally update
software, see my httpsync, published in DDJ in July 1999.

Httpsync is client-side only software, which compiles and
runs on BSD/Linux/Unix and Windows.

For the server side, use any old WWW server.

Since Httpsync uses port 80 HTTP, it isn't usually hard
to punch holes in firewalls or use proxies to enable
the transfers.

As I see it, the proprietary data, not the software, is
what RedHat has formed that business around.  There
is nothing anti-FSB with that, is there?
