The way we used to do that was to distribute a .plt file. Nowadays, we
recommend using planet for that, but you'd have to issue a command to
download it after drscheme is installed.

If you go the planet route, then telling them to (require (planet
...)) would also trigger running whatever code you'd want, and I
expect that code can go register the dlls? Unless DrScheme can't be
running at the time you do that, in which case you'd have to tell them
to run the command 'planet install ...', but is that beyond them?

If you go the .plt route, the same thing applies; you can create a
.plt that runs some code when it is installed to set up the
environment.
