I am writing a lisp server that accepts connections from clients; each
client will be assigned a new package at connection.
Each client package will inherit, depending on the client profile,
symbols from other pre-existing packages (applications).
The client will be able to send lisp commands to the server, and the
server will execute the commands in the client's package
(after checking that the commands are valid and do not access any data
outside its assigned package).
At client connection, the server need to save some data related to the
client in the clients package. The pre-existing
functions will be using these data defined by the server on connection.
I am not sure I am using the right strategy, but I am trying my first
ideas, and I hope I will gain more insights on the whole
application to allow me to make better choices to implement this whole
