Hm well you're asking for a native Linux vSphere client so why not trying an already available Open Source native Linux vSphere client?
vEMan - VMware ESX/ESXi Manager (Click here to go to the Open Source vSphere client for Linux)
If you miss something in vEMan let me know (Support Forum at the above link) - give it a try .. you may not need a Windows VM anymore at least for the most tasks and developing vEMan hasn't stop yet.. ;o)
