Yes, many MS products can be licensed on a per processor basis under SPLA. Microsoft Office is not one of these. SPLA is actually the easiest of MS's licensing offerings to understand and comply with. A pity they didn't check the article content with anyone who knows anything about it.

Windows 2008 Remote Desktop Services with Remote Desktop Experience pack (which gives you essentially a complete Win7 experience) is how you do it under SPLA. That would be legal under SPLA.
