User Account Login Login on your AIX server

I want to learn AIX. I would like to find someone who would be willing to give me a login to their AIX home lab server. My intent is to poke around and discover the similarities and differences of AIX compared to other *NIXs.
I am a UNIX admin so I can think of what some immediate concerns may be:

Will this person be malicious and try to damage my install or hack me or someone else?

No

I would be willing to grant a reciprocal arrangement. I have a lab with a few Cisco routers and Solaris and HP servers (most are pizza boxes). I can provide access one of those.
I have about 10 HP servers that I am not using and would give one in trade for AIX access.

This is not likely to happen and is a fairly unreasonable request given the current state of computer security. AIX is not a platform for which you can run a "home" version on a PC like you do Linux. It is based on IBM hardware and it is fairly unlikely anyone is just going to give you an account to poke around on their box.
