The issues include:

What are you doing with TCP/IP?

If you want a simple client you get to use the entire 64K (telnet, ftp, 
email).

If you want to use it via a redirector to attach to a file server then you 
have a problem:  The TCP/IP code takes up most of the 64K now you want to 
load a word-processor to access files on the server?


Another issue is how to physically attach it.
