Is it possible to set up Android in ad-hoc peer-to-peer wifi mode? For example, I would like to have one phone broadcast a message, and have all peers in the network receive the broadcast, without having a server. I would like to use wifi since bluetooth range is more limited.

Here's a bug report on the feature you're requesting.
It's status is "reviewed" but I don't believe it's been implemented yet.
you can connect your android device to a known ad-hoc network.
edit /system/etc/wifi/tiwlan.ini
WiFiAdhoc = 1
dot11DesiredSSID = <your_network_ssid>
dot11DesiredBSSType = 0
edit /data/misc/wifi/wpa_supplicant.conf
ctrl_interface=tiwlan0
update_config=1
eapol_version=1
ap_scan=2
if that is too simplistic, see these instructions.
Your answer is Wi-Fi direct which is made available with ICS. Here is a link for explanation in Android doc
I don't think it provides a multi-hop wireless packet routing environment. However you can try to integrate a simple routing mechanism. Just check out Wi-Share to get an idea how it can be done.
