I recently ran into a tool called Pen. Pen is a lot like other reverse

This makes it ideal work as an RA, because the load balancer (ok its a
proxy but close enough) can fail over to any node without having to
worry about synchronizing configuration files.

I have tested the RA with multiple running instances of Pen and
everything seems good. Finding a pen packages is easy and building
from sources is trivial as well. Once you get the RA installed it is
very easy to create load balancing groups on the fly.
Sounds good. If you wish to contribute the RA, please contact
Alan Robertson (in the cc) to resolve any possible legal issues.
I've attached the standard information on contributing something to the
project.
If you can have your boss send me an email as described in the
attachment, then we can include it.
Thanks!

Attached is text for two proposed permission letters for contributing to

If anyone has suggestions for wording on these letters, then please
speak up! ;-)
OK... I got good suggestions from the most excellent David Ham. I've
incorporated them, and have produced version 2 of the suggested disclaimer
letters.
Again, feedback is quite welcome!

This is "VERSION 2" of sample letters disclaiming interest by company XYZ
in the Linux-HA work done by FooBob. If FooBob's XYZ management knows
how to GPG sign their emails, that would be ideal (though its not necessary).
The main part of all these letters is:
1) XYZ is aware FooBob is contributing code to Linux-HA
2) XYZ consents to this contribution under the license
terms of the project
If you want to add something which says "and it's OK for FooBob to
claim copyright on this work", then more power to you -- BUT --
the project doesn't need that. I created one sample letter at
the end which does this.
If your company has its own procedures for this kind of "release
of intellectual property", then you'll probably have to follow
those. That's how alanr got his contributions released from Lucent.
They even released him from copyright ownership issues.
The main thing: Get a letter which states (1) and (2) above.
Email is easier for me to deal with, but I can deal with paper
if need be.

If you're doing this on company time, this is a good start...

To: Alan Robertson <[EMAIL PROTECTED]>
From: FooBob's management at XYZ company
Date: Today
This letter is to certify that FooBob has XYZ company's permission to
contribute to the open source Linux-HA project, and that the XYZ company
consents to him or her to doing so under the license terms of the
Linux-HA project.
----------------------------------------------------------------------
If you're doing this on your own time, then something like this
might be appropriate.
----------------------------------------------------------------------
To: Alan Robertson <[EMAIL PROTECTED]>
From: FooBob's management at XYZ company
Date: Today
This letter is to notify you that we are aware that FooBob is
contributing to the open source Linux-HA project on his or her
own time and with his or her own resources. Without prejudice
to any copyright or other claims between the XYZ company and
FooBob, the XYZ company consents to FooBob contributing to
the Linux-HA project under the license terms of that project.
----------------------------------------------------------------------
If you're doing this on your own time, and they're willing to sign it,
this letter is also a good choice...
