Andre:
In terms of using TCP directly or HTTP, the choice really revolves around
the source system, the target system and what's in between. If the client
and server are both .NET and you do not need to worry about firewalls in
between them, use the TCP channel with a binary formatter (the default).
This scheme will not work, however, if one of the endpoints is not .NET or
if there are firewalls in between the endpoints. The firewalls (or some
routers) will reject traffic not originating or destined to port 80.
In these cases, you still have an "efficiency" option. You can send
binarized data over the HTTP channel. This won't be quite as efficient as
sending the information over the TCP channel directly, but it does offer a
nice balance of speed and flexibility.
I have not hsed the genuine channels product, but I have seen mention of it
around the remoting newsgroups. I believe it is a set of classes that
simplifies using remoting channels, and implements "difficult to implement"
functionality such as remoting callbacks, etc. I am interested to see other
repsonses to this part of you question as a way of learning a little bit
more about what it does and perhaps how it works.
Hope this helps,
