I don't see how they would benefit from being rewritten in go.

Goblin was a fun way to learn go, not a project to be useful.

However i would be happy to see some new programs written in go.

For example we lack a picture manipulation program.

I'd like to see one done the plan 9 way. ie layers as image(6) files

and a bunch of small filter programs taht work on them (like crop resample..)

And some interface holding this all together. (Maybe a graphics enabled acme?)
