According to our good friend Mark Hinkle, we have a good chance of being the next Red Hat. Now I assume he means this as a compliment, but I'm not sure we want to be the next Red Hat, I'd rathe be the next mySQL (sold recently for 1billion to Sun). No doubt Red Hat is a dominate player in the open source and operating system world, but a lot of there extra circular activities haven't done very well.
I should also note we're heavy uses of a few of their technologies including Libvirt and RHEL.
Mark's put together a nice list of the "new batch of up-and-coming open source software companies who are not yet venture backed but are developing interesting technologies and services." http://opensource.sys-con.com/read/529607.htm
Thanks for including us!
