No, actually you can find the game here: http://www.infinitespacegames.com/games/
It's the new site they set up for the Infinite Space Series. Wonder if they'll expand the series with a Infinite Space Pt. III. BTW, it's great the games have been pulled from Shrapnel. Weird Worlds in particular was seriously overpriced given it's age. It's great that it's now available from several new sources. BTW, if you buy it now, you get a new version with some improvements over the Shrapnel Games version. It's been on sale for about 12 days at Indie Game Stand, got it from there. It's also available on Steam now!
The first link on Digital Eel's website points there.
I guess all owners of the Shrapnel version will also receive new ways to download or keys for Steam by Digital Eel if they ask them per mail and provide payment details/ proof of buying it at Shrapnel.
