[IPython-dev] excepthook-like behavior in ipython

[Carl Smith]

Hi Fernando

Thanks for your input. I've used StarCluster, its really good, but for
what I'm trying to do, I found it easier to just use boto and do
things by hand. I really want lots of small VMs, one per user,
controlled by a single, larger server that exists to manage users and
their VMs. Each user would have complete control over their own
instance, but only via IPython. They wouldn't have/need anything on
their local machine besides a decent browser.

This is meant to be used to learn programming collaboratively.

It's not very difficult to do what I'm looking into doing, but it'd
not work well without stdin. I'm not familiar with IPython internals,
so I guess I'll just have to be patient. It's not especially urgent
anyway.

Again, thanks for you reply and all the hard work.

Carl
