Unfortunately, it seems that the end of IRIX is creeping closer- I was just poking around on the SGI website and it looks like they've dropped the big MIPS graphic systems (Onyxes) Linux is a fine system, but IRIX is very nice, too, and it's nice to have multiple sources of ideas to draw from (Indigo Magic is a pretty slick desktop, among other things SGI did.) The big advantage of Linux over xBSD looks to be filesystems- Linux has JFS and XFS. P.S.- I do know about 5dwm.org, and I look forward to seeing it.
