Connecting MIM Connector to Web Services Data Sources

Hello,

i wish to use MIM to connect to Data sources with Web Services exposed. Can I use

1. The PowerShell MA to achieve this ? How Reliable\efficient is this approach ?

2. Can i customize the Web Services Connector to achieve this for my various application identity data sources, even though the default Web Services Connector Projects are specific to Oracle, SAP, PeopleSoft etc.

Thanks
