Conventional Streaming and IIS7 Media

I'm thinking of modifying the next version of our video delivery software to be based on IIS7 smooth streaming, but I need to consider how it will handle the functionality we already get out of WMS2008. Particularly webplaylists.

We already have a lot of WMS servers set up with broadcast points, distributing feeds from WMEncoders and 3rd party public rtsp/mms streams and we use dynamic serverside playlists to protect our local content. We use a silverlight front end to play back dynamically generated ASX files to link them all together.

Can anyone tell me if the new webplaylists system can combine local WMV prerolls with conventional WMS broadcast streams?

Do all the entries in the smil playlist have to be local to the IIS server?

If I use webplaylists, will silverlight mediaelements be able to seek through the content? (At present if you use a WMS serverside playlist silverlight will always see it as nonseekable.)

Many of our clients like conventional streams specifically because it doesnt cache their pay-per-view content on the client. Do "smooth streaming" files get cached clientside? Is there any way to be sure that the clients are actually paying attention to the no-cache headers?

Any guidance would be appreciated.
