it is annoying that metacreations seems to be paying less & less attention to the mac community esp. with regards to metastream, the basket they're supposedly putting all their eggs in. the last version of ray dream (5.5) shipped with a pc exporter but without a mac exporter and their web site has no mac version for the latest version of the plugin/player. the very least they could have done is keep the last mac version (2.2) available for download. in any case if you want a copy of that version, drop me a line. it will read metastream files created with curious labs' metastream exporter, but this exporter offers no frills.
