Type Oriented Programming Uses

As noted there are many advantages to type oriented programming, apart from using it in a parallel language there are a number of other suggestions:

GUI Programming - GUI programming can be quite tiresome and repetative (hence the use of graphical design IDEs.) By using types this would abstract the programmer from many of the repetative issues.
Retrofit Existing Languages - The type approach could be applied to existing languages where a retrofit could be undertaken, keeping the programmer in their comfort zone but also giving them the power of type oriented programming.
Numerous Type Systems - The type system is completely separate from the actual language, it would be possible to provide a number of type systems for a single language, such as a parallel system, a sequential system etc...
