Thanks for the info Robert! I continue inline...

Yes, it's referenced in the URL I gave previously but, of course, I am 
primarily looking for a non-commercial solution.

Thanks for the extra info. I will have a look.

However, in case you're interested, now I am investigating this one 
(which I haven't managed to make it work yet but I suspect the reason is 
that I am running it with 2.0 Framework and I should use 1.1 or update 
the sources...):

http://www.codeproject.com/csharp/reachability.asp?df=100&forumid=15864&exp=0&select=540926

The author states that it supports pure bi-directional communication 
using Remoting (it's only a new channel type implementation like the one 
from Ingo), and that it's even simpler ("more lightweight" is the exact 
term used) than the Genuine Channels.

The only things I haven't clarified yet is the license of the code (I 
don't find it, although the fact of being published at codeproject 
smells that it's LGPL-like or at least GPL-like) and the scalability 
which I could support with this method. Hopefully I will post here my 
results if I go further, in case anyone would be interested.

Regards.
