Looks like a lot of "negotiations" have changed the outcome of the OOXML standards vote. OOXML is probably going to be voted as an ISO standard. Appears that I spoke too soon.
The next logical thing is get funding for another truly open document standard.
As Andrew Tannenbaum says, the good thing about standards is that there are so many to choose from!
If the open source waters are being muddied, muddy it a little more and move to the new standard. However long it takes. A document is one of the fundamental blocks of business transactions in an electronic world. Making it unreadable at some future date due to legal and technical reasons is clearly not in anyone's interest.
Royalty free, non discriminatory and under a standards body NOT controlled by any entity is what the target should be.
