Of course this is rather appropriately done on  the target.

This is an example of what should be done on a Linux PC. It does not 
involve any hardware stuff, as the socket interface is common to all 
Linuxes.

Any Linux Desktop software uses an X interface as a display. Hence an X 
server is running. VM now forwards the X-API towards the host OSes 
display. Nonetheless the X-API the client sees should be perfectly 
standard and should be usable via TCP/IP.

I did not try such a thing but this is the paradigm ox X11.

IMHO: in any case when using hardware features of the target are not 
necessary to do the work at hand.

I once used XMING on WinXP. That did work fine.

IMHO the developing environment for a Linux target  should not involve 
any Windows stuff.

I already provided lots of hints on how the porting might be done, so I 
can't help with approaches I would not recommend, anyway.
