The nearest direct equivalent is a Unix daemon, of which I know of two
"styles" offhand.  The simplest style is just a program which is
detached from the terminal and is always running.  The easiest way to do
this in Mono would be to use a shell script:

	nohup mono mydaemon.exe > /tmp/mydaemon.log 2>&1 &

The "nohup" detaches the program from the terminal, the > redirects

The final "&" puts the program into the background, so that the program

I'm not sure how portable "nohup" is, but it's apparently part of IEEE
Std 1003.1-2001, so hopefully it exists everywhere.

See also:

The more complex style is to use a "super daemon" which knows how to
spawn other daemons on demand.  This is what inetd and xinetd do; you
can Google for them for more information.

Eventually, this should be encapsulated by Mono's
System.ServiceProcess.ServiceBase class, but this hasn't been completed

Check the mono-list and mono-devel-list archives for more information.

Not that I know of.

Not really.  Hopefully I've provided enough information to feed Google.
