I'll echo what mpt said -- you can currently do this with either HTTP
Accept: headers or with HTML <object>. For example:
<p>
What is this?
<object data="captcha-jpeg.cgi?id=125135">
<object data="captcha-mp3.cgi?id=125135">
(This server only supports audio and visual CAPTCHAs.
For help, please contact ...)
</object>
</object>
<input type="text" name="captcha">
</p>
I don't really see a better way to do it.
