Writing API using administration service

Hello!

I'm building a PowerShell library to interact with SCCM. I want this library to be as portable as possible, so I don't want to depend on the SCCM cmdlets, because they require to install the full console, and only work in Windows machines.

I started using the administration service, because I thought being a REST based service would be the most portable thing possible. However, I have found that it still has many limitations.

• I have tried to do the following tasks using the Administration service but failed: Create a task sequence deployment, add a direct rule membership to a collection. I'm able to do this using WMI. Is it currently impossible to do these through REST?
• Does Microsoft plan to implement missing functionality to the admin service?
