Perhaps you could use arp-scan, but then you'd have to run as root:

$ arp-scan --interface=eth0 --localnet
Interface: eth0, datalink type: EN10MB (Ethernet)
Starting arp-scan 1.5.2 with 256 hosts (http://www.nta-monitor.com/tools/arp-scan/)
192.168.1.1     00:c0:9f:09:b8:db       QUANTA COMPUTER, INC.
192.168.1.4     00:02:b3:bb:5c:09       Intel Corporation
192.168.1.3     00:02:b3:bb:66:98       Intel Corporation
192.168.1.5     00:02:a5:90:c3:e6       Compaq Computer Corporation
192.168.1.6     00:c0:9f:0b:91:d1       QUANTA COMPUTER, INC.

You might use the information from the arp cache:

> arp -a 
localhost (10.37.129.2) at 0:1c:42:0:0:9 on vnic1 ifscope permanent [ethernet]
localhost (10.37.129.255) at ff:ff:ff:ff:ff:ff on vnic1 ifscope [ethernet]
localhost (10.211.55.2) at 0:1c:42:0:0:8 on vnic0 ifscope permanent [ethernet]
localhost (10.211.55.255) at ff:ff:ff:ff:ff:ff on vnic0 ifscope [ethernet]
fritz.slwlan.box (192.168.0.1) at 0:4:e:2b:28:16 on en1 ifscope [ethernet]

Either you parse the result of "arp -a" on Unix yourself or look at

http://libdnet.sourceforge.net/dnet.html

providing access to the ARP cache from Python.
