I made my calculation based on 1 day a month so 3%, just for the few times I need to work on a panorama that does not finish on my 16 GB machine.

So I dont knwo how many gigas you did made, so sorry if you're an old stager but most importand much more than having 64GB Ram Servers available is practise practise and much more practise. each single project will give you new sticks & bumpers you've to sturggle with. so getting familar with workflows is wise to do it with 18mm sphericals ....

the "addon" option of SSD I mentioned is more than that. so maybe rather reduce the 6discRAID5 to a RAID1 with 2 discs but do not miss the SSDs.
the setup is fit for next two years. a second Xeon can be added to add more 6cores/12threads and RAM can be upgraded up to 256GB with this setup and if you replace them to bigger ones than even up to 512GB.

autopano & memory calculation for RAM: http://www.kolor.com/forum/p87033-2011-08-11-11-53-58#p87033
So if you wanna do gigapixels on a regular job basis you need to save time and to make better use of the resources, I would use 64GB with trend to more.

Now I do occasionally work on 10-20GB file sizes, and this is heavy lifting. As you noted in your current config, that you could do things to the file in Photoshop, but when it came to saving it, things would have stood still or at least appeared to have done so. Why! Slow storage!!! ;-) You need to have a storage array fast enough to off load the data to disk/SSD, in this case you will need a nice fast array. With my current setup, which is a bit slow at the moment I can average 1GB/sec and peak at 4GB/sec thats with 2x 6 SSD's in RAID-0 which makes it RAID-00 of 12 disks (across two controllers), plus i have another 8 SSD RAID-0 for my OS/apps on a 3rd controller.

That cloud discussion, well for me it is not an option. I do not like cloud computing (altough I have a Dropbox account) for various reasons. I like to have full control on my work.
And beside that: the time that it will take to upload, process and download is more than when I do it on my local computer.
East, west, home's best. So to say.

Being positive always is a good idea
But to pin it down to facts: did you ever in real life worked a, letÂ´s say, 6 Gigapixel panorama via the cloud the way you suggest?

In my system:
Really fast temp/scratch-disks. SSDs in RAID 0.
Enough RAM to avoid heavy disk access (much faster than SDDs in RAID 0)
How to achieve that in VM's I don't know.
