For all of you guys who are trying to manage ESXi from OSX, it is now possible through VmWare Fusion 7 Pro.
I just upgraded my fusion from 6 to 7Pro (about $85) and I can manage my ESXi.
To connect to ESXi through Fusion, go to File / Connect to server and enter the ESXi credentials.
Thats it folks, and it works, finally.
Woohoo !

Update: You can only stop or start a machine ALREADY configured on ESXi.
If you want to create a new VM, you still need to go through vSphere apparently.
Well.. That sucks.. this got me happy for a little while..

Another update:
If a VM is turned off in your FUSION, you can export it to ESXi.
I did not find any way to import from ESXi to Fusion (option "Download from server" is grayed on all my VM on ESXi)
You can't create a new VM from scratch on ESXi directly from Fusion.
