Aside from running Flip4Mac 2.0.2 with Safari in Rosetta mode, no. Flip4Mac is supposedly busy at work on the unibin solution, but not a single word on the release date. It would be nice if they can provide at least a public beta with support for WMV9 (F4M plays earlier WM files as well, with an exception of WM DRM).
Yeah, I'm afraid you'll have to wait for the UB of Flip4Mac to be released. In the meantime, I believe you can check out PopWire, which might do the trick - haven't played around with it myself though, so I'm not sure....
