For those of us who just used helix as a boot-disk that happened to have some free tools on it, this is a completely insane idea. It will backfire on them. I have no doubt that people who wrote this free software will protest the idea of profit on the backs of their work.
Now, helix does have a bit of non-free stuff, but I didn't generally use it. I can understand there is a cost to that part of the CD.
In the meantime, its quite easy to make your own Ubuntu boot cd. Some care is needed to disable mounting of disks and swap. Otherwise, some packages that you might be looking for can be
found here in my PPA.
The
directions Ubuntu provides covers most of the process.
I happen to place an ssh server and public keys on ours so we can access machines remotely.
Feel free to comment if you've got any questions about how to make your own CD -- its worth it not only for the remote forensics capability, but also because you'll learn how to be self-reliant using free software.
