Enable lync user using FIM 2010

I wanted to lync for a user when the user is provisioned in AD. I have FIM 2010 which is provisioning the users in AD.

Wanted suggestion on this,

1- I am planning to call powershell commandlets of lync in metverse extension when user is created in AD.

2- Use Powershell MA for lync enabling and disabling. Can any one provide me the sample scripts for schema etc for PSMA lync ?

please advise which is a better method ?

Any further suggestion ?
