The Lighting Controller

Looking at hardware options to run ShowXpress, I found the DELL XPS 18" Portable All-in-one touchscreen computer. With a 5 hour battery, it becomes an 18" tablet but with full computing capabilities. Now if it could communicate wirelessly with the DMX interface, it would be great. A quick search reveals a standard for wireless USB, but can't find much product. Does anyone know anything about this? (Sony makes a similar PC.) Thanks!

For me its better using the chauvet's DMX wireless solution...
