Well, the projects that tried the typesystem were canceled, that's what I
wrote. The typesystem self is more in a frozen phase. Some experiments
are going on, but on a low priority level. The problem is that Erlang has
not been designed with a type system in mind. Adding one later is possible,
but at a certain cost w.r.t. the freedom of programming. We are investigating
whether we can find an acceptable compromise for things to give up.

However, I can recommend everyone to start using teh SpecWeb software in
order to make the datatype specifications. This is useful even without
a checking program.
