just done a bit of homework
oasis.org is not available (no surprise there)
4oasis.org is available
oasis4.org/net/com is available (although quite limiting)
oacs.org is not available
oacs.net is
I think maybe we should stick to oacs, and just pronounce it oasis. I do not think too many people would complain about oacs.net as the domain. Many years from now, people will wonder what the letters meant, (who remembers that esso comes from S-O or Standard Oil? DOS became doss. IBM? NCR? HSBC?)
If you ask me, the A in oacs, stands for Asskickin' although I am not so sure that that will fly with the suits :)
On second thoughts, oasis4 is not so limiting. Who remembers OS/2 and Lotus 123?? The new name could be oasis4 (harking to the oacs4 that finally severed ties with aD), and have different versions, begining with version 1.0
