The document I linked came straight from Google Search and you don't
need to agree to anything to view it. The document doesn't seem to
impose restrictions. QEMU has supported the VMDK format and so have
other open source tools for a number of years.
For anything more specific you could search VMware's website and/or
check with a lawyer.
