I can appreciate your enthusiam to install webguide, I suppose if you really wanted webguide you could do a virtual machine with it, but i do not have personal experiance trying it.
Suggested alternative;
try using Orb, MUCH BETTER
Well, I'm running SBS 2003 with a virtual server install with WHS on it. Works brilliantly. You could argue that there's some overhead, and that you can share media right from the SBS server (and some days I'm actually thinking of it), but still as it works I have just left it there. My mom is regularly uploading pics to her area (no I DO NOT live with my mom, she does that remote through the WHS web interface, thank you very much), and she can view all the latest pics of the grandchildren. I have our iTunes library there (both the files and the actual library) and all computers play that music beautifully. For practical reasons, I have not yet moved movies and TV over there, the reason being that when I began this setup, there was already too many gigs to copy over for my taste. Just lazy, otherwise I would. I run Webguide and it works brilliantly, once I got the codecs sorted out (a bit of a mess, but same on vanilla WHS). Webguide can be set up to read files on a share, which in my case incidentally would be the movie files.
The only issue i have is that it takes quite a while to copy files over to the VDH (which resides on the SBS server secondary HDD). It's like it's lagging every 15 seconds. However, I have no flaw in streaming music. I have not extensively tested streaming movies from the WHS VHD (as I have not copied them over) but I have made some tests and they were fine. Webguide streaming is no problems either.
I am not sure that Orb runs as a service. Does it? Don't want to be logged in to the server...
All in all, I'm happy, but I have to admit it's somewhat redundant. But once I got used to the backups, and the sharing with family and friends (mom was just one example) I do not want to live without it.
Oh, yes! Another great benefit: since WHS is in a workgroup and the SBS is on a domain, there is no problem sharing media with my wife's Mac. I can't get her computer to access shared drives in the domain, not even on the server, but access to the workgroup is no problems. So she shares the iTunes library.
Wow! I intended a short entry, one or two sentences max. Got carried away there... Typical me!
I haven’t been around for a while so sorry about the late reply
