Comcast (and virtually all ISPs) have truly stupid TOSes.  I believe that 
Comcast's states that you are not permitted to run any servers of any kind.  Of 
course, they don't block port 80, and turn a blind eye to anyone hosting their 
own webserver in-house, so long as they don't see gigs and gigs of data going 
out.  I run VNC on my home machines and have DynDNS setup  for my Comcast 
account.  Technically, I run "vnc server" on each machine, so that would be 
prohibited... but then again, Windows Remote Desktop is a stripped version of 
Terminal Server, so that too would be prohibited.  Heck... if you can remote 
into your router, THAT is even prohibited via the TOS!

I've been told by Comcast reps that they virtually NEVER even look at any of 
this stuff unless the end user gives them reason to, like massive amounts of 
data going out or broad port probing or the like.  Think about this... all IP 
phone services (including Comcast's) use something that acts as a server to 
respond to incoming calls... it sits and waits for data, and when data is 
received, it runs a series of processes and converts the call from digital to 
analog... but you don't see Comcast kicking people off of its network for using 
non-Comcast VOIP solutions!

Personally, and this is very much just an IMHO sort of thing... I never 
consider Comcast's TOS in things I do, because they themselves don't abide by 
it.

  you're saying it's illegal to run an SSH server? that makes no sense.

    I was so caught up in this that I didn't even think about that.
    Running an SSH server alone is probably technically a violation of the
    ComCast ToS.  As much as I wish I could still do this, you're right,
    I'm not going to be able to.  Thanks for pointing this out.

    This is a great idea, and I feel a little foolish for not doing this
    in my first e-mail.  First of all, for information on me and a little
    about my research, you can check out my university web page at
    http://www.cs.umd.edu/~randofu.  I'm working on this with Bobby
    Bhattacharjee and Mark Shayman.  I'd appreciate it if you didn't send
    them too many e-mails (since they're busy), especially since I've
    realized this won't be possible.  I'm just pointing this out because
    even though I'm withdrawing it, I don't want anyone to think that I
    was trying to do something shady.


    I'm going to go look into the Comcast ToS and see what I can do about
    this...  Hopefully I can get around it somehow.
