Unless something major has changed in the last 4 months, there isn't an X-server
that runs on Android.  I've done this. The way to achieve that is to run a
chroot copy of an Arm-linux, run the program inside that Linux plus a VNC server
the connect to your local arm-Linux using a VNC program from google's store.  It
sorta works, but not anywhere as well as most people would need.  It was a
curiosity to me. Nothing more.

X-servers and X-clients work backwards of what most C/S architectures involve.
The physical machine where you want to display things - THAT is the X-server.
The remote machine is where the X-client runs.  Last time I needed to help
someone understand it, wikipedia had a good explanation.

Having a fully functioning X-Server for Android would be nice. REALLY nice.  To
get the needed performance, I can't see that being written in java, so a native
build will be needed for each platform.

Ok, so back to your final question - how to run remote GUI programs on Android?
 VNC.  I wish there were a working NX client, since NX is 2x-3x more efficient
than VNC or RDP.  Don't forget that VNC usually doesn't include any encryption,
so do this on a LAN only, not over the internet without adding a VPN to the mix.

BTW, I have an A500 tablet.
I hope this helps.
