Open the .install file on the N800, and Application Manager will open
and install it for you.  If you read the .install file in a text editor
you'll see that it just specifies repositories and package names.

The dropbear ssh client/server and a terminal are available from
maemo-hackers.org.  Open the install file under "bora/it2007" at
http://maemo-hackers.org/wiki/OssoXterm on your N800 and the terminal
will be installed.  Then in Application Manager you can install the
dropbear client and server.

I believe memory cards are mounted noexec, and are vfat anyway.  Copy
the file to the home directory and chmod +x it.

You can get to the internet from inside a scratchbox, you probably need
to fix /etc/resolv.conf.  It defaults to 127.0.0.1 which is wrong unless
you run a local name server or cache.

Memory cards are just mounted file systems, you can simulate those
exactly by using a USB card reader.
