Talk about coincidence! I was just going to come update this thread when I received a notice about the above post.
I upgraded our vSphere Server Appliance from 5.5 to 6.0 yesterday. VCSA 6.0's web client appears to be working in Chrome on OS-X now! Even better, each VM's summary tab now includes links to "Download Remote Console" and "Launch Remote console" to open a separate window using VMware Remote Console (VMRC). There are now VMRC installers available for Windows and OS-X, with Linux in the works according to the download site. Long story short, I can actually use my desktop Mac for VMware stuff now without having to fall back to Windows...
