No problem, if it is used the way I suggest, not changing the current form but adding a link that will popup the editor window... if they use an ancient browser they can still use the normal form and not open the special editor one. What I suggest is simply like an addon that would popup an editor window such as the Insert Icon link you have when you reply here.
Anyway...
Netscape users? They still exist?!!! []/testimages/icons/laugh.gif[/]
My site is currently Netscape compativle, but they are under 0.4%, I do sense however that at sites intended for US visitors this percentage will grow. Like your case, I guess, if you are conscerned about them. Anyway... as I´ve said, it wouldnt create any real problem at all, just that they wouldnt be able to use that special feature. No big deal.
