It looks like Comcast is blocking remote assistance sessions from Verizon FIOS. I can connect fine from FIOS a PC on Hargray.com and Kuhncom.net networks, but when I try to connect to my mother's PC on Comcast, the initial connection attempt times out. When I use Verizon Wireless' EVDO Broadband network it connects without issue. There are no differences in PC configurations between the two connections. I am using my X60 in all scenarios, and since I can connect to other individuals on different networks using FIOS, I have to assume that Comcast is in fact blocking remote assistance connections from FIOS.
Comcast has already been chided by the FCC for its stance on Net Neutrality slowing and/or blocking peer to peer traffic. At yesterday's FCC's open public meeting (Gigaom article) on the subject at Stanford, they failed to show up. Comcast is already a lousy cable TV provider, now they want to add lousy to their Internet service. As competition grows from Verizon FIOS and others, I would think they would want to rethink their strategy but they seem to have their head in the sand. I also have to chide Verizon and the other large telecoms for not showing up at this meeting. I can understand that telecoms don't want more regulation, but if they want to avoid it they need to reign in the likes of Comcast.
This is not a positive environment for the consumer and I believe Congress needs to take some action.
