Improvements in vSphere 5 Update Manager makes installation of 3rd party host extensions easier than ever before, no more "esxupdate” or “vihostupdate” in CLI required. Here is example how you can deploy latest PowerPath/VE with Update Manager 5.0 to your brand new vSphere 5 cluster.
Download latest PowerPath/VE bundle zip and unzip it, in that bundle you should find ESXi patch EMCPower.VMWARE.5.7.b173.zip, copy this patch to a folder which is accessible from your vSphere Client. In vSphere Client open Update Manager from vCenter Server “Solutions And Applications”, select “Patch Repository” tab and click “Import Patches” on top right corner of window
In Import Patches dialog press “Browse…” and browse to folder you copied EMCPower.VMWARE.5.7.b173.zip, select it and click “OK”
Click “Next” to proceed with uploading patch to Update Manager
Patch will now upload and if upload was successful you will see confirmation message of new uploaded patch, you may click “Finish”
Next you need to create a host extension baseline, click “Baseline and Groups” tab and click “Create…”
Type in a name for your new baseline, for example “PowerPathVE” should do. Select “Host Extension” in Host Baselines menu and click “Next”
Search PowerPath patch that you uploaded a moment ago, type “powerpath” in “Patch Name” field, select PowerPath 5.7 and add it, click “Next” and you may click “Finish”
Now that you have your new host extension baseline ready you can go to the “Host and Clusters” view, select desired cluster and attach PowerPath/VE baseline to it
Now you may Scan and Remediate cluster, just select PowerPathVE host extension baseline group and proceed with normal patch installation process
If only licensing of PowerPath/VE would be easy as this! 
VMware has today released VMware Workstation 8 and Fusion 4 for general availability. One of the cool new additions of Workstation 8 is “Shared VMs” feature which allows you to remotely connect to VMs on other VMware Workstation instances, ESXi hosts or to even vCenter Server!
