[sugar] Activity bundle tutorial

[Don Hopkins]

Thanks a lot for writing the activity tutorial, and for answering 
questions about them!

I have some questions about activities, and would appreciate anything 
tips you can give me, please:

What's a good example of an activity that starts and manages another X11 
process, like Squeak?

What are the issues surrounding activities that are implemented as 
external processes, as opposed to activities implemented in Python?

Is it possible to program activities in Python that run in the Sugar 
"desktop manager" process (or whatever it's called), or do they run as 
separate Python processes?

I suppose that would make it possible to quickly start light weight 
activities, but it would not firewall them from each other and restrict 
their privileges... How's that intended to work?

Can you make light weight (to use an ancient term) "desk accessory" 
sub-activities that are built into the Sugar manager, that you can pop 
up and use quickly while in other activities? (Kinda like the chat 
window?) Are those considered activities, or are they called something 
else?

I'm interested to know what ways there are to hook into the Sugar user 
interface, and plug in various kinds of user interface thingamabobs.
