According to some people, there's this whole "Web 2.0" thing going on right now, and I'm glad to say that IlohaMail isn't completely left behind:

• TextDrive, a fairly prominent "Web 2.0 Hosting Company", appears to be using IlohaMail for hosted webmail service. It appears they may be switching to a Joyent product (they just merged with Joyent, so I don't blame them), but if they are, it hasn't happened yet...
  
• RoundCube, an OpenSource Ajaxy webmail project uses IlohaMail's IMAP library under it's hood. So, okay, it's only part IlohaMail, but that's what OpenSource is all about.
  
• Speaking of Ajax, the latest devel version of IlohaMail in CVS actually has some nifty Ajax features. People have reported some issues with it, but hopefully we get things stablized and out the door soon...
