Nice! Which makes me wonder why i even have to switch to my bash-shell to 
install this http egg. Wouldn't it be cool to see something like this?:

#0> (use http-client)
Error: (require) can not load extension: http-client
Do you want to install it? [y/n]: y
Query extension database...found http.egg
downloading http.egg from (www.call-with-current-continuation.org eggs 80)
...

For this to work, you would need the extension->egg-mapping
and a chicken-setup egg! ...ahh ignore me, i am just lazy...
