Sorry - I thought this was a pre sales area to ask questions about the software etc!
I don't really care about the lic side - I can buy more if necessary - was I asked was can I run it internal only on an XP or W2003 server using xampp or should I just build a linux server to host it internally from scratch.
Thanks,
You can really run it on any environment you choose - I've had success with running it on an old 512MB RAM Windows 98 I had in the corner. Of course, if you're looking between Linux and Windows I'd definitely go the Linux route just for simplicity.
