I'm pretty sure 10.6 and later explicitly allow virtualization of OS X Server, and both VMWare and Parallels allow you to install OS X in a VM.

This is just a UI issue - CUPS printers shared via Bonjour show up as Bonjour Shared while network printers show up as Bonjour on OS X.  On Linux there is no distinction made in the current UI.

> 2.  When adding the queue the OSX client does a CUPS-Get-PPD operation ONLY when adding the queue from the OSX server, which downloads the driver and configures any options that were configured on the server(IE: Extra trays).  It does not attempt this when adding the queue that's on the Linux server, as verified via access logs and sniffing the traffic.  The access and error logs look identical on both servers up until that point.

Remember that the AccessLogLevel directive will limit what is reported in the access_log file, but usually we just do a HTTP GET of /printers/printername.ppd instead of using CUPS-Get-PPD (which is used when adding a printer with a local driver).

However, this should "just work" so if you don't see the GET then please file a bug against OS X:
