2.2 froyo - Manually set a hostname for IP address (i.e. /etc/hosts equiv.?)

I am a web developer and am developing our website on my local desktop machine. I have an android phone (htc desire running android 2.2). I want to test what our web application looks like on android. I can connect to the same wifi network as my desktop machine, however we make use of several hardcoded fake domain names in our web application. On my Ubuntu Linu7x desktop machine I use /etc/hosts to set these domain names to local IP addresses.

Is there anyway to do this on android? I want "foo.xyz" (our testing domain name) to point to 172.31.1.67 (my internal desktop machine). Is there any way to do this without rooting the phone (as my android phone is not rooted now)
