Why not just send you a few stills or rehearsal video from a cell phone? It's quick, requires nothing special as far as computers or internet and in my opinion would provide more than enough detail for your review. No need to complicate things.
Oh and about iChat not being serious enough... We haven't tried it yet but with SnowLeopard and FCP, you can share the HD edit window in realtime for online instant collaboration. For years the best way to convert sequential still files to video was with Quicktime or iMovie. We still use iDVD for a bunch of stuff that is far faster and easier than DVDSP. Our profession (video in general) has more to do with capable, talented people utilizing the right resource than with specific tools that might impress a client. (Don't read that statement wrong, I'm not saying an HDV camera compares to RED.)
