Dear Gharai,
Thank you for your concern about our work.
Our group have interested in HDTV over IP and is performing ongoing projects about it.
Information of this is available from:
Actually, we have been concerned about Ultra Grid . 
So, your comments cheers up our group and we expect to do some works with Ultra Grid and your team.
>From now on, I am going to test the Ultra Grid and read the documents about it . 
Thank you for your concern again.

	Excellent work!   I'd also like to bring to your attention related work
	with UltraGrid.
	UltraGird is a high definition collaboration tool.  UltraGrid nodes can
	send/receive close to ~1 Gbps of uncompressed HD content (we are now in
	the process of building UltraGrid nodes with 10 GigE NICs to
	accommodate full uncompressed  HDTV).
	We have also integrated UltraGrid with AccessGrid with the following
	two services: uvRecevierService and uvSenderService.
	This code is available from the project web-site:
