Yes they can.
As Chris says they can. And as you say there are concerns, so I shall not bore you with all of them.
But there are a huge difference in how Windows and OSX at handling such a setup.
The FMP and FMS uses some of the same library files (in Windows called DLL:s). And in Windows that means that they literally are using the same files. Which means that if FMP crashes (for some unknown reason) there are a risk that it will drag FMS down with it. Causing file damage.
OSX on the other hand make them totally separate in memory. Thus make it much safer.

Thank you Magnus,
I am experiencing 'issues'! They don't seem to play well together (Windows 7, Pro, 64Bit) So I think the way forward is a VM. Does anyone have any experience of doing this? Are there any 'gotchers'?
although they can exist on the same machine I would suggest that a part of testing the viability of a solution that will be hosted is determining how it behaves on both LAN and WAN connections.
