Install XI 2.0 on Unix/AIX anyone done it ?

Has anyone installed XI 2.0 on Unix/AIX system ? Any major issues or specific OSS notes on this. We are running APO on Unix/AIX and would like to run XI on the same operating system/platform, because of 64 bit and in-house basis experience, but we don't want to be bleeding edge.

Thanks, W.H. Sharp
