	IBM have talked about it in this paper:
	
	http://www.research.ibm.com/journal/sj/384/eustice.html
	
	They have been using their TSpaces server and an XML
	description called MoDAL in their concept of
	a Universal Information Appliance (UIA).
	XML is sent to/from the UIA device and the TSpaces
	server.
	
	In the paper it says:
	
	'future versions of the UIA may communicate with TSpaces
	 over HyperText Transmission Protocol (HTTP), via a Web
	 server, using a transcoding proxy such as WBI'
	 
	and:
	
	'Universal communication protocol--The UIA and application
	 services, like active calendar, require a universal protocol
	 to communicate with TSpaces. HTTP is a possible choice for
	 several reasons. Most TSpaces clients can conveniently execute
	 a Web server, URL-based locators provide a natural global naming 
	 scheme, and HTTP is a simple and widely used protocol for 
	 markup-language communications, such as MoDAL programs and XML
	 action interfaces.'
