That was Redline Smalltalk, which they've also pushing quite a bit. Their indiegogo campaign managed to raise 17.000$ so that the core dev can work full time for a while on the project.
I had two problems with Redline: if I remember correctly it's supposed to be file- instead of image-based. I'm not very optimistic about that, but maybe it will be alright - I sure hope so. The second thing is that JVM is not exactly my favorite environment.
However, every effort for bringing Smalltalk back to life - or rather back to mainstream - is praiseworthy and I'm very glad such effort are undertaken.
Image basedness, and the IDE microcosm in general is the single reason why I dislike Smalltalk, which is otherwise a very cool and well thought out language.

There's precedents for file-based Smalltalks. Basically, don't ##ck with your source files manually, and use VCS. Problem (pretty much) solved.
