IRM / RMS Enabling an Excel document

Apr 8, 2008 at 5:03 PM
I am using this library to create excel (xslx) documents on my web server before sending it down to the client's browser and this works FANTASTIC! Thanks so much for the excellent work.
My next piece of functionality is to now take the xlsx document that has been produced and protect it using Microsoft RMS (Rights Management Server), the evolution of Office IRM.
At this moment I have no idea how exactly to do it; but I believe it is possible to do with the Permission Object on an Office document; as shown here

Is there any "easy" way to do this with this library, or am I going to have to throw away all my work thus far and this brilliant package just for this one "tiny" feature? I hope not!

Any input / guidance would be great.
