Remote Differential Compression API Licensing and Use Rights.

Hi,

Can anyone tell me please what Microsoft product Remote Differential Compression API is licensed under?

The API is documented here: h t t p : / / t e c h n e t . m i c r o s o f t . c o m / e n - u s / l i b r a r y / c c 7 5 4 3 7 2 . a s p x.

If a commercial product was written that leveraged this API (and not DFS), would the resulting product be limited to hosts running Windows Server OSE's like 2008R2 or also desktop OSE's like Windows 7?

Thanks in advance for the help.
