I have tried, it doesn't work. Tileproxy would need the code included in it to work. It would make the cache run fast.
I am going to use an old proliant server with an old minimum 256 graphics card, run fsx / Prepar3d at minimum graphic levels, then network the other machines via wideview. The server will run tileproxy from the net and the other machines will have tileproxy running in offline mode. The SCSI drives and the 4 dual cores should make tileproxy run pretty hard. However, it may cause a miss rate. There is only one way to find out.....
