I'm going to play a bit of the devil's advocate here.
When I Googled this term, I expected to see "zip," but what I saw were over 5,000 Google (SERP?).
It's even defined in the Free dictionary.
Now, undeveloped, it truly is regfee.
However, it COULD be developed into something really cool and, perhaps, money-making.
When I first started this biz, Jay Westerdal (former owner of DomainTools) said something very astute on his blog: that success in this biz often goes to those who set trends, not follow them.
Will it be difficult to develop this site?
Probably.
But I have to say that wysiwyw IS a catchy acronym and not really all that difficult to remember.
Good luck in what you decide about this domain.
