Why not consider shadow copy.

<blockquote>
 Shadow copying enables assemblies that
 are used in an application domain to
 be updated without unloading the
 application domain. This is
 particularly useful for applications
 that must be available continuously,
 such as ASP.NET sites.
</blockquote>

Make the programs very simple shells. Then have them watch (FileWatcher) for updates to folder where they were loaded from (and where updates are delivered). Then dynamically reload the AppDomain.

See <a href="http://msdn.microsoft.com/en-us/library/ms404279.aspx" rel="nofollow">here</a> and <a href="http://bartdesmet.net/blogs/bart/archive/2006/07/29/4146.aspx" rel="nofollow">here</a> for more info.

<blockquote>
 You can use the properties of the
 AppDomainSetup class as follows to
 configure an application domain for
 shadow copying:
 
 Enable shadow copying by setting the
 ShadowCopyFiles property to the string
 value "true". By default, this setting
 causes all assemblies in the
 application path to be copied to a
 download cache before they are loaded.
 This is the same cache maintained by
 the common language runtime to store
 files downloaded...

Two best resources I have come across (both use BITS, which capably handles an unreliable connection).

<ul>
<li><a href="http://msdn.microsoft.com/en-us/magazine/cc188766.aspx" rel="nofollow">Write Auto-Updating Apps with .NET and the Background Intelligent Transfer Service API</a></li>
<li><a href="http://windowsclient.net/articles/appupdater.aspx" rel="nofollow">.NET Client Applications: .NET Application Updater Component</a></li>
</ul>

I'm writing a suite of programs for client PCs --

<ul>
<li>a Windows Service</li>
<li>a user-space Windows Forms application</li>
</ul>

I need to be able to publish an updated version of these programs and have the client PCs automatically and transparently (with no user interaction) update themselves. This update will be done over an unreliable 3G connection (EvDO). The applications will be continuously running, so the update will have to gracefully shutdown the service / close the applications, and then spin them up again after the update.

Before I spend time rolling my own solution, are there any pre-existing solutions for something similar?

Note: ClickOnce doesn't work here because of the Windows Service as well as several other reasons. I also can't take advantage of BITS because I'm running against Windows Azure, which lacks the BITS IIS plugin.
