It's only a beta (a kind of inside joke if you read the author's blog) but it certainly does the trick. I'm not sure if most users really know what Rendezvous is or why they would need a browser for it but if you do, IMHO this is the best offering so far. The Applescript triggers option is a stroke of genius that offers lots of flexibility for what this can do for you. I also like the "announce" feature although I'd love to be able to tweak what it says (without writing a new Applescript :-) ).
