Google'd and Yahoo'd...seen hundreds of ideas mostly based on
heartbeat. In fact I most recently was looking into Red Hat's Global
File System and clustering:
http://www.redhat.com/gfs/
http://www.redhat.com/cluster_suite/
Trying to figure out how Red Hat is accomplishing these things with
open source, or if they are adding their own proprietary background
stuff.
Look at CentOS. If it's in that (I believe it is) then it's OSS.
Now completely off topic..I just read a bit on CentOS website. Am I
correct in thinking that they're litterally redistributing what RedHat
Enterprise is? Even their documentation is cut/paste from RedHat with
RedHat logo's. I love the phrase they use 'prominent North American
Enterprise Linux vendor'.
RHEL is built by RH from RH source. CentOS is built by the CentOS team
from RH source, as far as licencing and trademarks allow. They are
obliged to make some changes.
I think the term 'prominent North American Enterprise Linux vendor'
arose following some nastiness from RH lawyers.
At the time of RHL 7.x, I could download it from RH and install it on my
machines, and I was running RHL. I could burn CDs and distribute them at
a LUG and that too was RHL. However, if I had a few left over and sold
them to a few mates, even at a nominal price, that was _not_ RHL.
That's RHL logic, not mine, and I believe it's a fair summary of RH
guidelines of the time limiting the use of its trademarks. I imagine
they're substantially the same now.
However this seems to answer my question about what RedHat Enterprise
really is..all open source.
_Mostly_ open source. Someone who has RHEL4 or 5 might comment in what
is in RHEL that's not (likely) in the equivalent CentOS.
