Hmm... I'll have to see whether something like this works to install  
my teachpacks.  At present, I tell students (and Computing Center staff)

1. Make sure your computer is connected to the Internet.
2. Start DrScheme.
3. From the “Language” menu, “Choose Language”, then select “Module”.
4. Click “Run”.
5. At the “>” prompt in the bottom half of the screen, type
(require (planet "install.ss" ("sbloch" "tiles.plt" 1 12)))
exactly like that, with the parentheses and quotation marks and all.  
After
a few seconds (or possibly a few minutes, if the server is slow), you  
should see the message
“Wrote file “tiles.ss” to installed-teachpacks directory.”
6. Likewise, type
(require (planet "install.ss" ("sbloch" "sb-world.plt" 1 4)))
You should get the message “Wrote file “sb-world.ss” to installed- 
teachpacks directory.”
7. From the “Language” menu, “Choose Language”, then click on the trian-
gle next to “How to Design Programs”, then select “Beginning Student”.
8. From the "Language" menu, "Add Teachpack...".  You should see  
"tiles.ss"
and "sb-world.ss" on the right hand side.  Double-click one of them.
Repeat with the other one.
9. Click "Run".  You should see a message like
Welcome to DrScheme, version 4.1.3 [3m].
Language: Beginning Student custom; memory limit: 128 megabytes.
Teachpacks: tiles.ss and sb-world.ss.

Of course, I'm using "require" in an unusual way, as a remote  
installer: the "install.ss" file, at load time, writes another file  
into the installed-teachpacks directory, which in turn requires from  
planet the module I'm actually interested in.  There must be a better  
way....
