I am also writting my own OS. You can read about it in the WWW as:

> the name as I wasn't alone at that time.

So, why can't you change it now?

I agree. But any language can have persistence added to it ( see
the Texas system in )

Smalltalk/Self bytecodes are also a good choice.

Ok. My system doesn't do this, but is close.

I don't think you can get rid of a nanokernel-like system. Something
must field the interrupts.

Almost all new OSes have this. Also, agent based programming is
the "in" thing in networks.

I do this with the normal "user objects".

Good choice.

I use Self. It is very good and getting much better!

I think it is a great idea!

Feel free to write me if you want more details about my work. I hope
to update my WWW pages later this week with some real information :-)
