Most user visible Select features ARE available for Iyonix.
I wrote to ROL explaining why I was letting my Select subscription lapse (after 2 years of subscribing). It was mainly because I could find precious few advances over RO4 that made it worthwhile me contributing to the scheme anymore especially for OS upgrades targetted at obsolete computers.
I also said that if certain Select modules such as the improved CDFS and thumbnail filer were to be made available as stand alone products for the Iyonix then I'd be interested in buying them.
I have had no reaction to either my email or letter I sent. Since then WSS have released CDROMFS and PhotoFiler for the Iyonix. So accordingly as ROL are not interested in my business anymore WSS get my money. Thus very much a lost sale for ROL.
PhotoFiler from WSS is now Iyonix happy so thumbnailing (including Artworks files) can be had on the Iyonix. Or you could use something like Thump.
