There are a whole bunch of classs in the System.Net libraries like the
webrequest and webresponse classes that can help you work with http data,
including https. Requests can be as simple WebRequest myRequest =
WebRequest.Create(http://www.contoso.com) but for https you may have to work
with the certificate. Take a read of this.

You can do remoting .

...........or use something like psexec

Either way, not all your code needs to be local.

All of the .net managed languages complile to the same thing, so its the
same regardless of whihc language you choose. Just get a good obfuscator.
There are some (slamander I think) that can compile to native code. I have
never tried it however, you 'll need to fish about.

VS.NET as a tool can generate class and method stubs from UML.
